Abstract
Since the release of the third version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III), biological psychiatry has been systematically applying its classification reasoning to social phenomena of many natures. From this perspective, the discourse of trauma gained relevance and events of devastating magnitude began to receive neurobehavioral interpretations until finally being recognized less for their cultural and subjective effects than for the physiological changes they cause. By a narrative review, this study aims to analyze the transition of traumatic rationality from the 19th century, when trauma was associated with the cognitive concept of memory, to the 20th century, when this phenomenon was finally attached to neuroscientific research on stress. The plurality of conceptual models and deterministic paradigms can contribute to the fact that trauma research produces multifactorial coping protocols more appropriate to the human experience of post-traumatic suffering.

Azoulay R, Gilboa-Schechtman E. The scarring impact of status loss in social anxiety: An evolutionary perspective. J Anxiety Disord 2022; 90:102600.

Abstract
Evolutionary models suggest that social anxiety (SA) is associated with sensitivity to status loss. These models make several additional predictions concerning the strength as well as the specificity of the association between post-event distress (PED) following status losses and SA. First, the strength of this association is postulated to be enhanced in men, especially following status losses inflicted by other men (intra-male status losses). Second, given the evolutionary postulated relationship between social status and physical fitness, sensitivity to status loss in SA is expected to extend to physically threatening events. We examined these predictions in four online samples (total N = 1123; 59% females, 27% above the cutoff for clinically elevated SA). In all studies, participants recalled social status-loss events and rated the emotional and distressing impact of these experiences. In two samples, participants also identified and recalled physically threatening events. Our findings were consistent with evolutionary predictions. SA was associated with PED following social status-loss events (β = 0.27). This association was stronger in men than in women (β = 0.40, β = 0.16, respectively). Moreover, the SA-PED association was especially enhanced following intra-male, compared to intra-female and inter-gender, status losses (β = 0.47, β = 0.26, and β = 0.17, respectively). Furthermore, SA was uniquely associated with PED following physically threatening events, over and above PED following social status-loss events (β = 0.21). Our data highlights the significant impact of socially and physically threatening events and delineates the scarring signature of such events in SA.

Abstract
BACKGROUND Childhood obesity (ChO) and eating disorders are on the rise, with concerning effects on health. Early prevention is essential as interventions after problems arise are costly and with a low success rate. In Norway, prevention of ChO has been largely weight-centered, without desired effects. Confident Body, Confident Child (CBCC) is a universal program aimed at preventing ChO, disturbed eating, and body image problems through a health-centered intervention for parents of children between 2 and 6 years. The current study is part of a cultural adaptation and translation of CBCC into Norwegian. METHODS Focus groups with parents (n = 16) and professionals (n = 11) were held around healthy eating, activity, and body image, with an emphasis on possible barriers for prevention as well as approaches considered helpful. The interviews were analyzed using interpretative phenomenological analysis. RESULTS Parents and professionals described parental stress connected to high standards, conflicting information, and parental comparison. A narrowing sense of normality around healthy living was described with little flexibility resulting in "all-or-nothing" thinking. Parents were anxious to say or do the wrong thing when regulating children's food intake and when faced with comments about appearance. Parents and professionals described parental concern around children not eating enough, and professionals described an increase in parents using food as regulation. Both parents and professionals expressed that having a child with overweight was tied to a sense of failure and shame. Interventions related to overweight seemed to increase stress and shame, further complicating follow-up. As an alternative, parents and professionals expressed a desire for interventions with normalizing information around "good-enough" parenting related to food and weight. DISCUSSION The described fear of doing something wrong and lack of flexibility is interpreted within a stress-sensitive understanding, where stress and shame can influence parents toward mobilizing action or disengagement, presenting as dichotomous behaviors of "all-or-nothing". CONCLUSION Interventions that can normalize parental concerns in a non-moralizing way may reduce stress and shame. CBCC addresses all the major concerns raised in this study, providing parents with evidence-based information they can implement into everyday life. The Norwegian cultural adaptation added extra emphasis on normalization and shame-reduction.

A non-canonical GABAergic pathway to the VTA promotes unconditioned freezing. Mol Psychiatry 2022; 27:4905-4917.

Abstract
Freezing is a conserved defensive behaviour that constitutes a major stress-coping mechanism. Decades of research have demonstrated a role of the amygdala, periaqueductal grey and hypothalamus as core actuators of the control of fear responses, including freezing. However, the role that other modulatory sites provide to this hardwired scaffold is not known. Here, we show that freezing elicited by exposure to electrical foot shocks activates laterodorsal tegmentum (LDTg) GABAergic neurons projecting to the VTA, without altering the excitability of cholinergic and glutamatergic LDTg neurons. Selective chemogenetic silencing of this inhibitory projection, but not other LDTg neuronal subtypes, dampens freezing responses but does not prevent the formation of conditioned fear memories. Conversely, optogenetic-activation of LDTg GABA terminals within the VTA drives freezing responses and elicits bradycardia, a common hallmark of freezing. Notably, this aversive information is subsequently conveyed from the VTA to the amygdala via a discrete GABAergic pathway. Hence, we unveiled a circuit mechanism linking LDTg-VTA-amygdala regions, which holds potential translational relevance for pathological freezing states such as post-traumatic stress disorders, panic attacks and social phobias.

Abstract
INTRODUCTION Literature has pointed the need for intervention programs specifically tailored to target the treatment needs of young offenders, as well as the need to test the efficacy of such programs through physiological indexes of emotion regulation (e.g., heart rate variability; HRV), complementing self-reports typically used as outcome measures. The PSYCHOPATHY.COMP is a 20-session individual intervention program based on Compassion Focused Therapy aiming to reduce psychopathic traits and disruptive behavior among young offenders through the development of a compassionate motivation, while stimulating the soothing system as a strategy to improve emotion regulation. Previous research with young offenders has shown decreases in vagally mediated HRV (vmHRV) when the soothing system is activated. This physiological pattern seems to mirror threat-like responses that contrast with relaxed states. METHODS To test the efficacy of the PSYCHOPATHY.COMP, a clinical trial was implemented encompassing a treatment (n = 56) and a control group (n = 53). Treatment participants attended the PSYCHOPATHY.COMP, while controls received the Treatment As Usual (TAU) delivered in Portuguese juvenile detention facilities. HRV data was collected throughout a standardized procedure (encompassing resting, reactivity and recovery phases) specifically designed to trigger the soothing system. Participants were assessed at pre-treatment, post-treatment and 6-months follow-up. RESULTS Although treatment participants continued to process the soothing system as unpleasant (with decreased vmHRV), they seem to become able to adaptively recover from the stimuli without avoiding it or resorting to maladaptive coping strategies. The physiological pattern was in line with participants' decreases in difficulties in emotion regulation across the assessment periods. In contrast, controls seemed to have actively employed coping strategies associated with increases in vmHRV not only when the soothing system was triggered, but also when recovering from the stimuli. Congruently, for controls, increases in difficulties in emotion regulation were found, with increases in the lack of emotional clarity across the assessment periods. DISCUSSION Findings offer new evidence for the efficacy of the PSYCHOPATHY.COMP program in improving emotion regulation in young offenders, assessed through both self-report and physiological measures. Additionally, findings support the assessment of the autonomic balance as a treatment efficacy index in future research, targeting the rehabilitation of these youth. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov, identifier NCT03971682.

Abstract
BACKGROUND Many people experience psychological trauma during their lifetime, often negatively affecting their mental and physical health. Post-traumatic growth is a positive psychological change that may occur in an individual after having processed and coped with trauma. This journey, however, has not been studied enough. AIM The purpose of this phenomenological study was to explore people's experience of suffering psychological trauma, the personal effects of the trauma and the transition from trauma to post-traumatic growth. METHODS A purposeful sample of seven women and five men, aged 34-52, were selected whose backgrounds and history of trauma varied, but who had all experienced post-traumatic growth. One to two interviews were conducted with each one, in all 14 interviews. RESULTS This study introduces a unique mapping of the challenging journey from trauma to post-traumatic growth through lived experiences of people who have experienced trauma as well as post-traumatic growth. Participants had different trauma experience, but their suffering shaped them all as persons and influenced their wellbeing, health and view of life. Participants described post-traumatic growth as a journey, rather than a destination. There was a prologue to their journey which some described as a hindering factor while others felt it was a good preparation for post-traumatic growth, i.e. to overcome difficulties at an early age. Participants described six main influencing factors on their post-traumatic growth, both facilitating and hindering ones. They also described the positive personal changes they had undergone when experiencing post-traumatic growth even though the epilogue also included heavy days. A new theoretical definition of post-traumatic growth was constructed from the findings. CONCLUSION The results suggest that the journey to post-traumatic growth includes a recovery process and certain influencing factors that must be considered. This information has implications for professionals treating and supporting people who have suffered traumas.

Abstract
Childhood adversity has been associated with elevated risk for psychopathology. We investigated whether development of functional brain networks important for executive function (EF) could serve as potential mediators of this association. We analyzed data of 475 adolescents, a subsample of the multisite longitudinal NCANDA (National Consortium on Alcohol and Neurodevelopment in Adolescence) cohort with completed measures of childhood trauma, resting-state functional brain connectivity data, and symptoms of internalizing and externalizing psychopathology at baseline and follow-up years 1–4. Using parallel process latent growth models, we found that childhood adversity was associated with increased risk for externalizing/internalizing behaviors. We specifically investigated whether functional connectivity of the dorsal anterior cingulate cortex (dACC) to brain regions within the cingulo-opercular (CO) network, a well-known EF network that underlies control of attention and self-regulation, mediates the association between adversity and symptoms of psychopathology. We found that childhood adversity, specifically child neglect was negatively associated with functional connectivity of the dACC within the CO network, and that this connectivity mediated the association between neglect and externalizing behaviors. Our study advances a mechanistic understanding of how childhood adversity may impact the development of psychopathology, highlighting the relevance of dACC functional networks particularly for externalizing psychopathology.

Something Scary Is Out There: Remembrances of Where the Threat Was Located by Preschool Children and Adults with Nighttime Fear. EVOLUTIONARY PSYCHOLOGICAL SCIENCE 2021.

Abstract
AbstractYoung children frequently report imaginary scary things in their bedrooms at night. This study examined the remembrances of 140 preschool children and 404 adults selecting either above, side, or below locations for a scary thing relative to their beds. The theoretical framework for this investigation posited that sexual-size dimorphism in Australopithecus afarensis, the presumed human ancestor in the Middle Pliocene, constrained sleeping site choice to mitigate predation. Smaller-bodied females nesting in trees would have anticipated predatory attacks from below, while male nesting on the ground would have anticipated attacks from their side. Such anticipation of nighttime attacks from below is present in many arboreal primates and might still persist as a cognitive relict in humans. In remembrances of nighttime fear, girls and women were predicted to select the below location and males the side location. Following interviews of children and adult questionnaires, multinomial log-linear analyses indicated statistically significant interactions (p < 0.001) of sex by location for the combined sample and each age class driven, in part, by larger frequencies of males selecting the side location and females selecting the below location. Data partitioning further revealed that males selected the side location at larger frequencies (p < 0.001) than the below location, whereas female selection of side and below locations did not differ significantly. While indicative of evolutionary persistence in cognitive appraisal of threat locations, the female hypothesis did not consider natural selection acting on assessment of nighttime terrestrial threats following the advent of early Homo in the Late Pliocene.

Abstract
Historically speaking, the behavioral tradition advanced functional analysis as a method of applying existing principles to novel situations. In the more than half a century since that idea was advanced, functional analysis has either fallen into disuse, as in most of applied psychology, or has been used but modified to a point that is virtually inapplicable elsewhere, as in applied behavior analysis work with severe developmental disabilities. In this paper we argue that the current challenges with COVID-19 present an ideal time to reinvigorate functional analysis by combining it with the growing body of evidence on processes of change, organized under an extended evolutionary meta-model. This new form of process-based functional analysis takes advantage of the strengths of contextual behavioral science, while opening avenues of fruitful interaction with other wings of intervention and evolutionary science more generally. Using the psychological flexibility model as an example, we show how this approach solves the key problems of classical functional analysis and helps professionals deal with novel challenges such as those posed by COVID-19. Humanity is now facing an extraordinary and unexpected situation. Behavioral science needs to rise to that challenge in a way that provides both immediate practical value and greater assurance of long-term benefits for our understanding of human complexity more generally. Process-based functional analysis can be a vehicle to do just that.

Abstract
Victims of urban violence are at risk of developing Posttraumatic Stress Disorder (PTSD), one of the most debilitating consequences of violence. Considering that PTSD may be associated with inefficient selection of defensive responses, it is important to understand the relation between motor processing and PTSD. The present study aims to investigate the extent to which the severity of posttraumatic stress symptoms (PTSS) is related to motor preparation against visual threat cues in victims of urban violence. Participants performed a choice reaction time task while ignoring a picture that could be threating or neutral. The EEG indices extracted were the motor-related amplitude asymmetry (MRAA) in the alpha frequency range, and the lateralized readiness potential (LRP). We observed a linear relation between longer LRP latency and a slower reaction time, selectively during threat processing (compared to neutral) in low PTSS, but not in high PTSS participants. Alpha MRAA suppression and the PTSS were also linearly related: the smaller the alpha MRAA suppression in the threat condition relative to neutral, the greater the PTSS. These results provide evidence that threatening cues affect motor processing that is modulated by the severity of PTSS in victims of urban violence.

Abstract
The clinical course of borderline personality disorder with persistent suicidal communication and self-destruction is often characterized by freedom-restricting interventions, long-term hospitalization, and a lack of commitment for disorder-oriented treatment. We present the course of a 31-year-old man who was offered the free choice between disorder-oriented treatment or discharge from in-patient treatment. The clinical decision to offer the choice to the patient was based on the judgment of given capacity of self-determination except for short periods of acute crisis. Deliberate refraining from the use of coercive interventions and demanding responsibility for change from the patient paved the way for psychotherapeutic treatment and the reactivation of his own skills.

Abstract
The practice of ethics in social science research is a reflexive process of self-review to define a profession's collective responsibility in the face of changing norms and expectations. In recent years, we have seen transformative changes in how society thinks about supporting sexual assault survivors, and how the scientific community thinks about our obligations to society. Decades of research on trauma and its impact has raised awareness about the needs of victimized individuals, giving rise to the trauma-informed practice movement, which emphasizes that service providers must center survivors' well-being in all interactions, decisions, and program practices. The field of sexual assault research helped give rise to this movement and provides empirical support for its guiding tenets, and in this article, we explore how to bring these ideas full circle to begin articulating trauma-informed principles for research. A trauma-informed perspective on research challenges scientists to go beyond the requirements of the Belmont Report (1979) and institutional review boards' (IRB) regulations to develop research procedures that fully support survivors' choice, control, and empowerment. Such reflection on participants' rights is particularly important given the open science movement sweeping academia, which calls on scientists to share their data publicly to promote transparency, replication, and new discoveries. Disseminating data could pose significant safety, privacy, and confidentiality risks for victims of sexual assault, so we need to evaluate what open science means within a trauma-informed framework. In this article, we examine three key stages of the research process-participant recruitment, data collection, and dissemination-and consider how trauma-informed principles could help, but also could complicate, research practices. We explore these tensions and offer potential solutions so that research on sexual trauma embodies trauma-informed practice.

Abstract
OBJECTIVE To identify evidence for dissociation as a cause of ongoing interpersonal violence. METHOD A systematic review of the literature retrieved from ten databases. RESULTS Fifteen studies yielded from our search strategy have been included in the review; eleven of these were longitudinal and four were experimental. The evidence indicates that pathological dissociation may contribute towards enduring interpersonal violence. Thus, dissociation may account for instances of repeated victimisation. There are similar indications concerning offenders, but study designs in this area allow one to draw fewer causal conclusions. There is some evidence that dissociation decreases information processing from the limbic system, which may be one underlying neurofunctional mechanism of persistent violence. CONCLUSION There is growing evidence for dissociation as a cause of interpersonal violence. However, the available evidence is still limited, and our review rather reveals an important research gap. Future longitudinal and experimental studies aimed at clarifying the role of dissociation in the context of violence should take into account the theoretical and empirical complexity around the concept of dissociation.

Abstract
Sexual violence is a devastating trauma with long-lasting effects on survivors' health and well-being. Despite the substantial impacts of the last 25 years of research, the prevalence of sexual violence has remained stable. It will be necessary to reconceptualize our work, challenging our theories, methods, and strategies for dissemination and implementation moving forward. We outline an intersectional, community-engaged approach for sexual violence research to center the stories of survivors who face systemic oppression and inequity. Finally, we suggest applications of this approach for justice, healing, and prevention to inform our collective work to end sexual violence.

Abstract
Post-traumatic stress disorder (PTSD), a diagnosis that may follow the experience of trauma, has multiple symptomatic phenotypes. Generally, individuals with PTSD display symptoms of hyperarousal and of hyperemotionality in the presence of fearful stimuli. A subset of individuals with PTSD; however, elicit dissociative symptomatology (i.e., depersonalization, derealization) in the wake of a perceived threat. This pattern of response characterizes the dissociative subtype of the disorder, which is often associated with emotional numbing and hypoarousal. Both symptomatic phenotypes exhibit attentional threat biases, where threat stimuli are processed preferentially leading to a hypervigilant state that is thought to promote defensive behaviors during threat processing. Accordingly, PTSD and its dissociative subtype are thought to differ in their proclivity to elicit active (i.e., fight, flight) versus passive (i.e., tonic immobility, emotional shutdown) defensive responses, which are characterized by the increased and the decreased expression of the sympathetic nervous system, respectively. Moreover, active and passive defenses are accompanied by primarily endocannabinoid- and opioid-mediated analgesics, respectively. Through critical review of the literature, we apply the defense cascade model to better understand the pathological presentation of defensive responses in PTSD with a focus on the functioning of lower-level midbrain and extended brainstem systems.

Abstract
People may suffer from an intruded fear memory when the attributable traumatic events no longer exist. This is of highly clinical relevance to trauma-induced mental disorders, such as posttraumatic stress disorder (PTSD). Mechanism underlying PTSD largely lies in the abnormal process of fear extinction and a functional imbalance within amygdala associated fear circuit areas. Previous evidence suggested central dopamine plays a key role in the regulation of the fear memory process, yet it remains unclear whether the intervention of dopamine modulators would be beneficial for the fear extinction abnormalities. The present study examined the performance of Pavlovian conditioned fear and the changes of dopamine profiles following a subchronic 14-day regimen of aripiprazole (a partial agonist of dopamine D2 receptors to normalize the condition caused by dopamine imbalance) in rats previously experienced a psychologically traumatic procedure of single prolonged stress (SPS). The results demonstrated that aripiprazole at 5.0 mg/kg reversed the SPS-impaired fear memory dysfunction and the SPS-reduced dopamine efflux in the amygdala. The present study suggests a therapeutic potential of subchronic treatment with aripiprazole in managing patients suffered from fear extinction problem.

Abstract
The dissociative disorders field and the hypnosis field currently reject the autohypnotic model of the dissociative disorders, largely because many correlational studies have shown hypnotizability and dissociation to be minimally related (r = .12). Curiously, it is also widely accepted that dissociative patients are highly hypnotizable. If dissociative patients are highly hypnotizable because only highly hypnotizable individuals can develop a dissociative disorder - as the author proposes - then the methodology of correlational studies of hypnotizability and dissociation in random clinical and community samples would necessarily be constitutively unable to detect, and statistically unable to reflect, that fact. That is, the autohypnotic, dissociative distancing of that small subset of highly hypnotizable individuals who repeatedly encountered intolerable circumstances is statistically lost among the data of (1) the highly hypnotizable subjects who do not dissociate and (2) subjects (of all levels of hypnotizability) who manifest other kinds of dissociation. The author proposes that, when highly hypnotizable individuals repeatedly engage in autohypnotic distancing from intolerable circumstances, they develop an overlearned, highly-motivated, automatized pattern of dissociative self-protection (i.e., a dissociative disorder). The author urges that theorists of hypnosis and the dissociative disorders explicitly include in their theories (a) the trait of high hypnotizability, (b) the phenomena of autohypnosis, and (c) the manifestations of systematized, autohypnotic pathology. Said differently, the author is suggesting that autohypnosis and autohypnotic pathology are unacknowledged nodes in the nomothetic networks of both hypnosis and dissociation.

Abstract
OBJECTIVE To determine the prevalence of physical, sexual and emotional abuse and physical and emotional neglect suffered by women with chronic pelvic pain (CPP) during childhood and whether these occurrences are associated with symptoms of pain, anxiety and depression. METHODS A case-control study was conducted on 154 women older than 18 years, 77 of them healthy and 77 with CPP. A history of sexual, physical, and emotional abuse and physical and emotional neglect was determined using the Childhood Trauma Questionnaire (CTQ). Anxiety and depression symptoms were determined using the Hospital Anxiety and Depression (HAD) scale. Pain intensity was determined using a visual analog scale (VAS). The quantitative variables were compared by the Wilcoxon test, and the qualitative variables were compared by the Chi-square test or exact Fisher test when appropriate. Correlation between the CTQ, HAD and VAS scores was estimated by the Spearman's p coefficient. Independent association of the variables with the presence of CPP was determined by logistic multiple regression analysis. RESULTS The prevalence of childhood maltreatment was 77.9% and 64.9%, respectively, for women with CPP and healthy women (p = 0.07). Emotional neglect was more frequent among women with CPP than among healthy women (58.4% versus 41.5%, p = 0.04). There was a moderate correlation between anxiety and depression symptoms and CTQ scores for women with CPP. Unemployment (OR = 4.15, 95% CI 1.73-9.94; ORadj = 3.30, 95% CI 1.26-8.55) was independently associated with the presence of CPP. CONCLUSIONS Women with CPP reported emotional neglect abuse more frequently than healthy women. There was a direct correlation between maltreatment scores and anxiety and depression scores. On the other hand, CPP was independently associated only with unemployment.

Abstract
SummaryThe traditional disease model, still dominant in psychiatry, is less than ideal for making sense of psychological issues such as the effects of early childhood experiences on development. We argue that a model based on evolutionary thinking can deepen understanding and aid clinical practice by showing how behaviours, bodily responses and psychological beliefs tend to develop for ‘adaptive’ reasons, even when these ways of being might on first appearance seem pathological. Such understanding has implications for treatment. It also challenges the genetic determinist model, by showing that developmental pathways have evolved to be responsive to the physical and social environment in which the individual matures. Thought can now be given to how biological or psychological treatments – and changing a child's environment – can foster well-being. Evolutionary thinking has major implications for how we think about psychopathology and for targeting the optimum sites, levels and timings for interventions.

Abstract
Sexual assault is a traumatic event with potentially devastating lifelong effects on physical and emotional health. Sexual assault is associated with gastrointestinal, neurologic, and reproductive symptoms, as well as obesity, diabetes, and chronic pain. With 1 in 3 women and 1 in 6 men experiencing some form of unwanted sexual violence in their lifetime, sexual assault is a significant public health problem that necessitates attention in the medical community. This review discusses relevant literature on the neurobiologic changes that occur as a consequence of sexual assault, such as how the brain responds during a traumatic experience and the impact of trauma on memory. Osteopathic considerations for trauma-informed care and practice and how all physicians can better serve patients with a history of sexual assault are also discussed.

Abstract
An interpretive phenomenological analysis sought to explore how people reporting moderate to high levels of dissociation experienced relationships with multidisciplinary hospital ward staff. Three superordinate themes were developed. First, the theme "multiple me and multiple them" explores the instability experienced by the participants as they managed their dissociative experiences alongside many inconsistencies. Second, "recognizing, meeting, or neglecting interpersonal and care needs" reflects on participants' needs within therapeutic relationships. Third, "between the needs of the internal system: navigating between 'better on my own' and 'someone to talk to'" discusses the confusion and understanding around dissociation and the importance of working with parts, not around them. Findings suggested that the current culture of some hospital wards directly influenced participants' distress, which could lead to further dissociation as a means of coping with perceived threats. Reflections on relational complexities and developing ward-based treatment are discussed.

Abstract
In cities throughout the United States, hundreds of thousands of sexual assault kits (SAKs) have not been submitted by the police for forensic DNA testing. Given recent media attention and public outcry about this problem, many jurisdictions with large numbers of untested SAKs are deciding to test all previously unsubmitted SAKs, which raises complex issues regarding when and how victims ought to be notified about what has happened to the kits that were collected during their medical forensic examinations. In this project, we collaborated with one community that has had large numbers of untested SAKs-Detroit, Michigan-to develop an empirically supported planning framework for how to create a victim notification protocol. This planning tool presents 12 discussion questions that can guide communities through the process of creating a victim notification protocol tailored to the needs of their local jurisdiction. In this article, we review the evidence (both practice and research based) that can inform discussions about each of these 12 key questions.

Abstract
BACKGROUND Posttraumatic stress disorder (PTSD) is associated with hyperarousal and active fight or flight defensive responses. By contrast, the dissociative subtype of PTSD, characterized by depersonalization and derealization symptoms, is frequently accompanied by additional passive or submissive defensive responses associated with autonomic blunting. Here, the periaqueductal gray (PAG) plays a central role in defensive responses, where the dorsolateral (DL-PAG) and ventrolateral PAG (VL-PAG) are thought to mediate active and passive defensive responses, respectively. METHODS We examined PAG subregion (dorsolateral and ventrolateral) resting-state functional connectivity in three groups: PTSD patients without the dissociative subtype (n = 60); PTSD patients with the dissociative subtype (n = 37); and healthy controls (n = 40) using a seed-based approach via PickAtlas and SPM12. RESULTS All PTSD patients showed extensive DL- and VL-PAG functional connectivity at rest with areas associated with emotional reactivity and defensive action as compared to controls (n = 40). Although all PTSD patients demonstrated DL-PAG functional connectivity with areas associated with initiation of active coping strategies and hyperarousal (e.g., dorsal anterior cingulate; anterior insula), only dissociative PTSD patients exhibited greater VL-PAG functional connectivity with brain regions linked to passive coping strategies and increased levels of depersonalization (e.g., temporoparietal junction; rolandic operculum). CONCLUSIONS These findings suggest greater defensive posturing in PTSD patients even at rest and demonstrate that those with the dissociative subtype show unique patterns of PAG functional connectivity when compared to those without the subtype. Taken together, these findings represent an important first step toward identifying neural and behavioral targets for therapeutic interventions that address defensive strategies in trauma-related disorders.

Abstract
RATIONALE Several lines of recent evidence suggest that endocannabinoids affect behavior by influencing the general patterns of challenge responding. OBJECTIVES Here, we investigated the brain mechanisms underlying this phenomenon in rats. METHODS The anandamide hydrolysis inhibitor URB597 was condensed into the tip of stainless steel cannulae, which were chronically implanted slightly above the prelimbic cortex (PRL) or the basolateral amygdala (BLA), two important regions of coping and endocannabinoid action. Thereafter, we investigated behavioral responsiveness to ambient light level in the elevated plus-maze and conditioned fear tests. RESULTS URB597 concentration was ~30 μg/mg protein in target areas; local brain anandamide levels increased threefold, without significant changes in 2-arachidonoylglycerol. High levels of illumination halved the time spent by controls in the open arms of the plus-maze. No similar decrease was observed in rats with URB597 implants in the PRL. High light decreased conditioned fear by 30 % in controls, but not in rats with prelimbic URB597 implants. Unresponsiveness to environmental challenges was not attributable to the anxiolytic effects of anandamide enhancement, as implants induced paradoxical anxiogenic-like effects under low light, which could be explained by effects on stimulus responsiveness rather than by effects on anxiety. URB597 implants targeting the BLA did not affect stimulus responsiveness. CONCLUSIONS Our findings show that elevated prelimbic anandamide signaling leads to less environment-dependent (more autonomous) behavioral responses to challenges, which is an attribute of active coping styles. These findings are discussed in light of two emerging concepts of endocannabinoid roles, particularly "emotional homeostasis" and "active coping."

Abstract
High levels of emotional intelligence (EI) have been associated with increased success in the workplace, greater quality of personal relationships, and enhanced wellbeing. Evidence suggests that EI is mediated extensively by the interplay of key emotion regions including the amygdala, insula, and ventromedial prefrontal cortex, among others. The insula, in particular, is important for processing interoceptive and somatic cues that are interpreted as emotional responses. We investigated the association between EI and functional brain responses within the aforementioned neurocircuitry in response to subliminal presentations of social threat. Fifty-four healthy adults completed the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) and underwent functional magnetic brain imaging while viewing subliminal presentations of faces displaying anger, using a backward masked facial affect paradigm to minimize conscious awareness of the expressed emotion. In response to masked angry faces, the total MSCEIT scores correlated negatively with a cluster of activation located within the left insula, but not with activation in any other region of interest. Considering the insula's role in the processing of interoceptive emotional cues, the results suggest that greater EI is associated with reduced emotional visceral reactivity and/or more accurate interoceptive prediction when confronted with stimuli indicative of social threat.

Abstract
There is a growing appreciation within the livestock industry and throughout society that animal stress is an important issue that must be addressed. With implications for animal health, well-being, and productivity, minimizing animal stress through improved animal management procedures and/or selective breeding is becoming a priority. Effective management of stress, however, depends on the ability to identify and quantify the effects of various stressors and determine if individual or combined stressors have distinct biological effects. Furthermore, it is critical to determine the duration of stress-induced biological effects if we are to understand how stress alters animal production and disease susceptibility. Common stress models used to evaluate both psychological and physical stressors in cattle are reviewed. We identify some of the major gaps in our knowledge regarding responses to specific stressors and propose more integrated methodologies and approaches to measuring these responses. These approaches are based on an increased knowledge of both the metabolic and immune effects of stress. Finally, we speculate on how these findings may impact animal agriculture, as well as the potential application of large animal models to understanding human stress.

Abstract
Evolution has endowed all humans with a continuum of innate, hard-wired, automatically activated defense behaviors, termed the defense cascade. Arousal is the first step in activating the defense cascade; flight or fight is an active defense response for dealing with threat; freezing is a flight-or-fight response put on hold; tonic immobility and collapsed immobility are responses of last resort to inescapable threat, when active defense responses have failed; and quiescent immobility is a state of quiescence that promotes rest and healing. Each of these defense reactions has a distinctive neural pattern mediated by a common neural pathway: activation and inhibition of particular functional components in the amygdala, hypothalamus, periaqueductal gray, and sympathetic and vagal nuclei. Unlike animals, which generally are able to restore their standard mode of functioning once the danger is past, humans often are not, and they may find themselves locked into the same, recurring pattern of response tied in with the original danger or trauma. Understanding the signature patterns of these innate responses--the particular components that combine to yield the given pattern of defense-is important for developing treatment interventions. Effective interventions aim to activate or deactivate one or more components of the signature neural pattern, thereby producing a shift in the neural pattern and, with it, in mind-body state. The process of shifting the neural pattern is the necessary first step in unlocking the patient's trauma response, in breaking the cycle of suffering, and in helping the patient to adapt to, and overcome, past trauma.

Critical periods for the neurodevelopmental processes of externalizing and internalizing. Dev Psychopathol 2015; 27:321-46.

Abstract
AbstractResearch on neurobiological development is providing insight into the nature and mechanisms of human neural plasticity. These mechanisms appear to support two different forms of developmental learning. One form of learning could be described as externalizing, in which neural representations are highly responsive to environmental influences, as the child typically operates under a mode of hedonic approach. A second form of learning supports internalizing, in which motive control separates attention and self-regulation from the immediate influences of the context, particularly when the child faces conditions of avoidance and threat. The dorsal cortical networks of externalizing are organized around dorsal limbic (cingulate, septal, lateral hypothalamic, hippocampal, and ventral striatal) circuits. In contrast, the ventral cortical networks of internalizing are organized around ventral limbic (anterior temporal and orbital cortex, extended amygdala, dorsal striatal, and mediodorsal thalamic) circuits. These dual divisions of the limbic system in turn self-regulate their arousal levels through different brain stem and forebrain neuromodulator projection systems, with dorsal corticolimbic networks regulated strongly by locus coeruleus norepinephrine and brain stem raphe nucleus serotonin projection systems, and ventral corticolimbic networks regulated by ventral tegmental dopamine and forebrain acetylcholine projections. Because the arousal control systems appear to regulate specific properties of neural plasticity in development, an analysis of these systems explains differences between externalizing and internalizing at multiple levels of neural and psychological self-regulation. In neuroscience, the concept of critical periods has been applied to times when experience is essential for the maturation of sensory systems. In a more general neuropsychological analysis, certain periods of the child's development require successful self-regulation through the differential capacities for externalizing and internalizing.

Abstract
Here we present a theory of human trauma and chronic stress, based on the practice of Somatic Experiencing(®) (SE), a form of trauma therapy that emphasizes guiding the client's attention to interoceptive, kinesthetic, and proprioceptive experience. SE™ claims that this style of inner attention, in addition to the use of kinesthetic and interoceptive imagery, can lead to the resolution of symptoms resulting from chronic and traumatic stress. This is accomplished through the completion of thwarted, biologically based, self-protective and defensive responses, and the discharge and regulation of excess autonomic arousal. We present this theory through a composite case study of SE treatment; based on this example, we offer a possible neurophysiological rationale for the mechanisms involved, including a theory of trauma and chronic stress as a functional dysregulation of the complex dynamical system formed by the subcortical autonomic, limbic, motor and arousal systems, which we term the core response network (CRN). We demonstrate how the methods of SE help restore functionality to the CRN, and we emphasize the importance of taking into account the instinctive, bodily based protective reactions when dealing with stress and trauma, as well as the effectiveness of using attention to interoceptive, proprioceptive and kinesthetic sensation as a therapeutic tool. Finally, we point out that SE and similar somatic approaches offer a supplement to cognitive and exposure therapies, and that mechanisms similar to those discussed in the paper may also be involved in the benefits of meditation and other somatic practices.
