Abstract
BACKGROUND Diurnal emotional experiences seem to affect several characteristics of sleep architecture. However, this influence remains unclear, especially for positive emotions. In addition, electrodermal activity (EDA), a sympathetic robust indicator of emotional arousal, differs depending on the sleep stage. The present research has a double aim: to identify the specific effects of pre-sleep emotional states on the architecture of the subsequent sleep period; to relate such states to the sympathetic activation during the same sleep period. METHODS Twelve healthy volunteers (20.1 ± 1.0 yo.) participated in the experiment and each one slept 9 nights at the laboratory, divided into 3 sessions, one per week. Each session was organized over three nights. A reference night, allowing baseline pre-sleep and sleep recordings, preceded an experimental night before which participants watched a negative, neutral, or positive movie. The third and last night was devoted to analyzing the potential recovery or persistence of emotional effects induced before the experimental night. Standard polysomnography and EDA were recorded during all the nights. RESULTS Firstly, we found that experimental pre-sleep emotional induction increased the Rapid Eye Movement (REM) sleep rate following both negative and positive movies. While this increase was spread over the whole night for positive induction, it was limited to the second half of the sleep period for negative induction. Secondly, the valence of the pre-sleep movie also impacted the sympathetic activation during Non-REM stage 3 sleep, which increased after negative induction and decreased after positive induction. CONCLUSION Pre-sleep controlled emotional states impacted the subsequent REM sleep rate and modulated the sympathetic activity during the sleep period. The outcomes of this study offer interesting perspectives related to the effect of diurnal emotional influences on sleep regulation and open new avenues for potential practices designed to alleviate sleep disturbances.

Abstract
Cephalometric parameters are thought to influence static posture. The present work evaluates the relationships between skeletal class or facial divergency, on one hand, and body posture, on the other hand. ANB and FMA angles were measured from profile cephalograms in twenty healthy adults. From each, stabilograms were recorded, with eyes open or shut, and with or without disclusion splints. Without splints, ANB and FMA proved to correlate with the accuracy of postural control. Adding splints changes the average position of the center of pressure exerted on the ground by the body, the anterior-posterior axis, and this effect is consistent with that of the typology. It also alters the displacement of the center of pressure on the same axis. These effects depend on whether the eyes are open or closed. The data reinforces the notion of the impact of cephalometric parameters and their mechanical changes on the static posture. They invite us to take greater account of postural impact of splints used in orthodontic practice.

Abstract
The objectives of the present study were to (i) better characterize visual emotional experience in patients with temporal lobe epilepsy (TLE), (ii) identify clinical risk factors that might be predictive of a change in emotional experience, and (iii) study the relationships between emotional experience and psychobehavioral/quality-of-life factors. Fifty patients with TLE and fifty matched controls evaluated the emotional content of unpleasant, pleasant, and neutral pictures with respect to their valence (unpleasant-to-pleasant) and arousal (low-to-high) levels. Demographic, cognitive, and psychobehavioral data were recorded for all participants, and clinical data and factors related to quality of life were also collected for patients with TLE. There were no significant differences between the group with TLE and the control group in terms of valence evaluations. However, arousal scores for neutral pictures were significantly higher in patients with TLE than in controls. There was also a nonsignificant trend towards lower arousal scores for pleasant pictures in patients with TLE than in controls. Although none of the recorded clinical factors were found to be related to emotional experience, the level of apathy was predictive of greater arousal experience for neutral pictures in patients with TLE. In conclusion, emotional experience appears to be modified in TLE and might be related to apathy. Changes in emotional experience should be taken into account in studies in which neutral stimuli are used to establish a baseline level when assessing emotional and cognitive processing.

Abstract
Processing and storage in visuospatial working memory (VSWM) seem to depend on attention-based mechanisms. In order to explore the effect of attention-attractive stimuli, such as emotional faces on VSWM performance, ERPs were obtained from 20 young adults while reproducing spatial sequences of six facial (happy and neutral) and non-facial control stimuli in inverse order. Behavioral performances revealed that trials with happy facial expressions resulted in a significantly higher amount of correct responses. For positive emotional facial stimuli, N170 amplitude was higher over right temporo-parietal regions, while P2 amplitude was higher over frontal and lower over parietal regions. In addition, LPP amplitude was also significantly higher for this type of stimuli. Both behavioral and electrophysiological results support the notion of the domain-general attention-based mechanism of VSWM maintenance, in which spatial to-be-remembered locations might be influenced by the emotional content of the stimuli.

Abstract
BACKGROUND The priority processing of peripherally presented affective stimuli was recently shown in healthy individuals to divert attentional resources dedicated to foveal processing. Here we investigated the influence of sub-clinical levels of anxiety and depression on this bias. METHODS Eighty-four participants were submitted to psychological tests that evaluate anxiety and depression levels. Then, they had to make speeded responses to the direction of left- or right-oriented arrows that were presented foveally at fixation. Each arrow was preceded by a peripherally presented pair of pictures, one neutral and one emotional, unpleasant or pleasant. Thus, the direction of the foveal arrow was either congruent or not with the peripheral location of the previously presented emotional picture. Data analysis focused on the differences of reaction times between congruent and incongruent conditions, which assess the spatial response bias in the task. RESULTS A main effect of state-anxiety was observed suggesting that the higher the level of state-anxiety, the greater the congruence effect. LIMITATIONS Since the obtained result relates to subclinical anxiety levels, its generalization to anxiety disorders remains tentative. CONCLUSIONS State-anxiety appears to modulate the propensity to be influenced by emotionally salient information occurring in peripheral vision, independently of its relevance to the ongoing behavior. The long-term persistence of a high level of alertness for emotional cues in visual periphery could contribute to the causation and the maintenance of anxiety disorders.

Abstract
Recent studies suggest that patients with anorexia may express dissociated cognitive and physiological reactivities to emotional stimuli. The present research aimed to compare subjective and autonomic responses to pleasant, unpleasant and neutral scenes during a categorization task and an activation rating task in anorexic (AN), alexithymic (AL), depressed (DEP) and control participants (CONT). The participants first categorized pictures according to their emotional valence, followed by a rating of their activation level, concomitant with the recording of skin conductance responses (SCRs). Main findings showed that the AN patients presented major difficulty in categorizing pictures, particularly neutral ones. Contrary to the AL participants, this difficulty did not induce significant increases of SCR amplitude in the AN patients. In the second task, the AN patients rated the intensity of activation of unpleasant pictures higher than the AL participants and that of pleasant ones higher than the AL and CONT participants. In addition, no significant linear correlation was observed between the intensity of activation ratings and SCR amplitude in the AN, AL or DEP participants contrarily to what was observed for control participants. This lack of relation suggests a non-specific disconnection between physiological and cognitive self-reported responses to emotional stimuli. Our results highlight a specific form of emotional processing in the AN patients distinct from that observed in alexithymia or depression and characterized by a dissociation between cognitive and physiological responses. This kind of disconnection could be associated with emotional regulation processes and may benefit the AN patients by lowering the psychological stress response.

Abstract
Current research in affective neuroscience suggests that the emotional content of visual stimuli activates brain–body responses that could be critical to general health and physical disease. The aim of this study was to develop an integrated neurophysiological approach linking central and peripheral markers of nervous activity during the presentation of natural scenes in order to determine the temporal stages of brain processing related to the bodily impact of emotions. More specifically, whole head magnetoencephalogram (MEG) data and skin conductance response (SCR), a reliable autonomic marker of central activation, were recorded in healthy volunteers during the presentation of emotional (unpleasant and pleasant) and neutral pictures selected from the International Affective Picture System (IAPS). Analyses of event-related magnetic fields (ERFs) revealed greater activity at 180 ms in an occipitotemporal component for emotional pictures than for neutral counterparts. More importantly, these early effects of emotional arousal on cerebral activity were significantly correlated with later increases in SCR magnitude. For the first time, a neuromagnetic cortical component linked to a well-documented marker of bodily arousal expression of emotion, namely, the SCR, was identified and located. This finding sheds light on the time course of the brain–body interaction with emotional arousal and provides new insights into the neural bases of complex and reciprocal mind–body links.
