Abstract
The current study aimed to investigate alterations of event-related potentials (ERPs) microstate during reward anticipation in subjects with schizophrenia (SCZ), and their association with hedonic experience and negative symptoms. EEG data were recorded in thirty SCZ and twenty-three healthy controls (HC) during the monetary incentive delay task in which reward, loss and neutral cues were presented. Microstate analysis and standardized low-resolution electromagnetic tomography (sLORETA) were applied to EEG data. Furthermore, analyses correlating a topographic index (the ERPs score), calculated to quantify brain activation in relationship to the microstate maps, and scales assessing hedonic experience and negative symptoms were performed. Alterations in the first (125.0-187.5 ms) and second (261.7-414.1 ms) anticipatory cue-related microstate classes were observed. In SCZ, reward cues were associated to shorter duration and earlier offset of the first microstate class as compared to the neutral condition. In the second microstate class, the area under the curve was smaller for both reward and loss anticipation cues in SCZ as compared to HC. Furthermore, significant correlations between ERPs scores and the anticipation of pleasure scores were detected, while no significant association was found with negative symptoms. sLORETA analysis showed that hypo-activation of the cingulate cortex, insula, orbitofrontal and parietal cortex was detected in SCZ as compared to HC. Abnormalities in ERPs could be traced already during the early stages of reward processing and were associated with the anticipation of pleasure, suggesting that these dysfunctions might impair effective evaluation of incoming pleasant experiences. Negative symptoms and anhedonia are partially independent results.

Abstract
Introduction An extensive literature regarding gender differences relevant to several aspects of schizophrenia is nowadays available. It includes some robust findings as well as some inconsistencies. The identification of gender differences and the understanding of their explanations may help to clarify the underlying etiopathogenetic mechanisms of specific aspects of the disorder. Objectives The present study aimed at investigating gender differences on premorbid, clinical, cognitive and outcome indices, as well as their impact on recovery, in a large sample of patients with schizophrenia recruited within the multicenter study of the Italian Network for Research on Psychoses. Methods State-of-the-art instruments were used to assess the investigated domains. Group comparisons between male and female patients were performed on all considered indices. The associations of premorbid, clinical and cognitive indices with recovery in the two patient groups were investigated by means of multiple regressions. Results Males with respect to females had a worse premorbid adjustment – limited to the academic dimension – an earlier age of onset, a higher frequency of history of substance and alcohol abuse, more severe negative symptoms (both avolition and expressive deficit), positive symptoms and impairment of social cognition. No gender difference was observed in neurocognition nor in the rates of recovery. Conclusions Although males showed some disadvantages in the clinical picture, this was not translated into a worse outcome. This finding may be related to the complex interplay of several factors acting as predictors or mediators of outcome. Disclosure No significant relationships.

Abstract
Persistent negative symptoms are associated with worse outcome in both first-episode and chronic subjects with schizophrenia. The identification of these symptoms in recent-onset subjects is still controversial as retrospective data are often unavailable. The prospective assessment of persistence of negative symptoms might represent a valid alternative but the length of the persistence is still to be established. The present study investigated the prevalence of negative symptoms of moderate severity, unconfounded by depression and extrapyramidal symptoms at baseline in a large cohort of patients in the early stage of a schizophrenia-spectrum disorder, recruited to the OPTiMiSE trial. Persistent unconfounded negative symptoms were assessed at 4, 10 and 22 weeks of treatment. Symptomatic remission, attrition rate and psychosocial functioning was evaluated in subjects with short-term (4 weeks) persistent negative symptoms (PNS) and in those with negative symptoms that did not persist at follow-up and/or were confounded at baseline (N-PNS). Negative symptoms of moderate severity were observed in 59% of subjects at baseline and were associated to worse global functioning. PNS were observed in 7.9% of the cohort, unconfounded at both baseline and end of 4-week treatment. PNS subjects showed lower remission and higher attrition rates at the end of all treatment phases. Fifty-six percent of subjects completing phase 3 (clozapine treatment) had PNS, and 60% of them were non-remitters at the end of this phase. The presence of short-term PNS during the first phases of psychosis was associated with poor clinical outcome and resistance to antipsychotic treatment, including clozapine.

Abstract
Introduction Cognitive deficits are considered a key feature of schizophrenia due to their substantial influence on the psychosocial outcome of subjects affected by this disorder. Several studies showed that moderate to severe cognitive impairments, including dysfunctions of social cognition, are already present during the early phases of the illness, in subjects with first-episode psychosis (FEPs). Psychosocial interventions, such as social skill training (SST), could therefore be implemented already upon occurrence of the first episode of psychosis to improve the overall functional outcome of schizophrenia, which represents to date an unmet need in the care of these patients. Objectives The study aims to evaluate the use of SST to enhance social skills and real-life functioning in FEPs. Methods The sample included 7 FEPs (age between 15 and 40). The SST intervention included 30 sessions lasting 2 hours and delivered twice a week. Psychopathology, neurocognition, real life functioning, functional capacity and social cognition were assessed at baseline ad after training. Paired samples t-tests were performed to evaluate the effects of the intervention. All subjects were treated with second generation antipsychotics. Results Significant improvements were observed in negative symptoms, social cognition, problem solving skills, as well as in global functioning (all p<0.05). Within real-life functioning, the improvement was greater for the domain of interpersonal relationships. Conclusions These preliminary findings suggest that SST might complement pharmacological treatment in FEPs to improve functional outcome in these subjects. Further studies with a higher sample size and a longer follow-up are required in order to confirm the present results.

Abstract
Negative symptoms are considered a core feature of schizophrenia. They are present since the prodromal phase and tend to persist more than other psychopathological dimensions in the chronic stages. The domain of apathy has attracted research efforts for the strong association with poor functional outcome. This negative symptom domain is observed in a number of neuropsychiatric disorders and might have both overlapping and distinct pathophysiological mechanisms. In schizophrenia it can be secondary to other aspects of the disorder, such as positive symptoms and depression, to drug side effects and/or social isolation, often observed in affected subjects. When primary to schizophrenia, apathy is conceptualized in terms of a reduction of the voluntary activity due to a lack of interest and motivation for goal-directed behavior initiation and persistence. In a percentage of subjects, apathy tend to persist and do not respond to available pharmacological and psychosocial treatments. The assessment of this domain in patients with schizophrenia using internationally recognized criteria for its definition, as were recently developed in other neuropsychiatric disorders, might help disentangle the different pathophysiological mechanisms. In the presentation, studies of apathy in schizophrenia will be illustrated to highlight the relationships with cognitive dysfunction, other psychopathological dimensions and functional outcome using state of the art instruments to assess the construct in schizophrenia.DisclosureProf. Mucci has been a consultant and/or advisor to or has received honoraria from Gedeon Richter Bulgaria, Janssen Pharmaceuticals, Lundbeck, Otsuka, Pfizer and Pierre Fabre.

Abstract
Introduction Social cognition and skill deficits have been largely documented in subjects with schizophrenia (SCZs), and have a strong influence on the functional outcome of these subjects. Different behavioural interventions have been developed to target and improve social skills in SCZs. For instance, the Social Skills Training (SST) focuses on improving communication skills and assertiveness to facilitate disease management, independent living and real-life functioning of SCZs. SST seems also to have an impact on negative symptoms and social cognition. Objectives The study aims to evaluate the effectiveness of SST in improving social cognition and negative symptoms in SCZs. Methods The sample included 8 chronic SCZs (age between 18 and 60), who completed 6 months of SST. The intervention consisted of two weekly group sessions of 2 hours each. We assessed psychopathology, neurocognition, real-life functioning, functional capacity and social cognition at baseline and after training. Paired samples t-tests were performed to evaluate the differences of the variables considered after completing the treatment. Results Significant improvements in negative symptoms (p<.05), social cognition (p<.05), functional capacity (p<.001), activities of daily living (p<.001) and interpersonal relationships (p<.011) were found. Conclusions The present findings suggest that SST might ameliorate social cognition and negative symptoms which are generally not influenced by antipsychotic treatment. The integration of pharmacological and SST interventions might have an impact on major determinants of poor real-life functioning in SCZs.

Abstract
Background
Measles is a vaccine-preventable infectious disease and it remains one of the leading causes of infant mortality globally. The World Health Organization (WHO) has adopted the goal of eliminating measles and rubella. Detection and control of communicable diseases would not be possible without accurate laboratory results regarding when and where a particular disease circulates.
Methods
WHO/Europe therefore works with all Member States to steadily improve the quality of the laboratory data in order to determine the Region's progress towards measles and rubella elimination. For this purpose coordinates the European Measles and Rubella Laboratory Network (MR LabNet). National labs in this network undergoes regular external quality assessment through an annual accreditation programme.
Results
In Italy, a Sub-national Reference Laboratories Network for measles and rubella (MoRoNET) has been developed since March 2017 and currently includes 15 laboratories. MoRoNet was developed following the indications of the MR LabNet. It is accreditate, coordinated and supervised by the National Reference Laboratory.
Conclusions
Strengthening the role of national laboratories in overseeing the performance of subnational laboratories has become a critical need in order to properly monitor the Region's measles and rubella elimination efforts. MoRoNet permits to Italy to develop a country-specific work plan for establishing national networks and oversight mechanism, including preliminary monitoring and evaluation indicators compliant with MR LabNet standards. This is very significant not only to optimize the participation in national and regional processes to verify disease elimination, but also to strengthen the quality of vaccine-preventable disease surveillance.

Key messages
MoRoNet has permitted to Italy to develop a country-specific work plan for establishing national networks and oversight mechanism, compliant with WHO MR LabNet standards. MoRoNet network has permitted to optimize the participation in processes to verify disease elimination, but also to strengthen the quality of vaccine-preventable disease surveillance.

Abstract
OBJECTIVE The study aimed to explore premorbid academic and social functioning in patients with schizophrenia, and its associations with the severity of negative symptoms and neurocognitive impairment. METHOD Premorbid adjustment (PA) in patients with schizophrenia was compared to early adjustment in unaffected first-degree relatives and healthy controls. Its associations with psychopathology, cognition, and real-life functioning were investigated. The associations of PA with primary negative symptoms and their two factors were explored. RESULTS We found an impairment of academic and social PA in patients (P ≤ 0.000001) and an impairment of academic aspects of early adjustment in relatives (P ≤ 0.01). Patients with poor PA showed greater severity of negative symptoms (limited to avolition after excluding the effect of depression/parkinsonism), working memory, social cognition, and real-life functioning (P ≤ 0.01 to ≤0.000001). Worse academic and social PA were associated with greater severity of psychopathology, cognitive impairment, and real-life functioning impairment (P ≤ 0.000001). Regression analyses showed that worse PA in the academic domain was mainly associated to the impairment of working memory, whereas worse PA in the social domain to avolition (P ≤ 0.000001). CONCLUSION Our findings suggest that poor early adjustment may represent a marker of vulnerability to schizophrenia and highlight the need for preventive/early interventions based on psychosocial and/or cognitive programs.

Abstract
BACKGROUND The increased use of the MATRICS Consensus Cognitive Battery (MCCB) to investigate cognitive dysfunctions in schizophrenia fostered interest in its sensitivity in the context of family studies. As various measures of the same cognitive domains may have different power to distinguish between unaffected relatives of patients and controls, the relative sensitivity of MCCB tests for relative-control differences has to be established. We compared MCCB scores of 852 outpatients with schizophrenia (SCZ) with those of 342 unaffected relatives (REL) and a normative Italian sample of 774 healthy subjects (HCS). We examined familial aggregation of cognitive impairment by investigating within-family prediction of MCCB scores based on probands' scores. METHODS Multivariate analysis of variance was used to analyze group differences in adjusted MCCB scores. Weighted least-squares analysis was used to investigate whether probands' MCCB scores predicted REL neurocognitive performance. RESULTS SCZ were significantly impaired on all MCCB domains. REL had intermediate scores between SCZ and HCS, showing a similar pattern of impairment, except for social cognition. Proband's scores significantly predicted REL MCCB scores on all domains except for visual learning. CONCLUSIONS In a large sample of stable patients with schizophrenia, living in the community, and in their unaffected relatives, MCCB demonstrated sensitivity to cognitive deficits in both groups. Our findings of significant within-family prediction of MCCB scores might reflect disease-related genetic or environmental factors.

Abstract
IntroductionAn impairment of premorbid adjustment (PA) has been regarded among poor prognostic indicators of schizophrenia. Some discrepancies in the literature suggest the usefulness of further characterizations of its impact on different aspects of the disease.AimsThe present study aimed to investigate the association of poor PA with psychopathology, neurocognition and real-life functioning in patients with schizophrenia recruited within the multicenter study of the Italian network for research on psychoses. functioning during childhood and adolescence (early adjustment) was assessed also in a group of healthy controls (HC) and one of unaffected relatives of patients (UR).MethodsGroup comparisons were performed between patients with poor and those with good PA. Differences in frequency of poor early adjustment were investigated among patients, HC and UR.ResultsPatients with poor PA, as compared to those with good PA, showed earlier age of onset, more severe negative symptoms and disorganization, greater impairment on all cognitive domains with the exception of attention/vigilance and worse real-life functioning in the considered areas (interpersonal relationships, community activities and work abilities). The pattern of poor early adjustment was more frequent in patients with respect to UR and HC and, to a less degree, in UR with respect to HC.ConclusionsOur findings confirm that poor PA in schizophrenia is associated with poorer illness outcome, and offer a further characterization of PA impact on different psychopathological and cognitive domains. They also suggest that poor early adjustment is a candidate endophenotype of schizophrenia, occurring in patients and their unaffected relatives.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
BACKGROUND The study aimed to subtype patients with schizophrenia on the basis of social cognition (SC), and to identify cut-offs that best discriminate among subtypes in 809 out-patients recruited in the context of the Italian Network for Research on Psychoses. METHOD A two-step cluster analysis of The Awareness of Social Inference Test (TASIT), the Facial Emotion Identification Test and Mayer-Salovey-Caruso Emotional Intelligence Test scores was performed. Classification and regression tree analysis was used to identify the cut-offs of variables that best discriminated among clusters. RESULTS We identified three clusters, characterized by unimpaired (42%), impaired (50.4%) and very impaired (7.5%) SC. Three theory-of-mind domains were more important for the cluster definition as compared with emotion perception and emotional intelligence. Patients more able to understand simple sarcasm (⩾14 for TASIT-SS) were very likely to belong to the unimpaired SC cluster. Compared with patients in the impaired SC cluster, those in the very impaired SC cluster performed significantly worse in lie scenes (TASIT-LI <10), but not in simple sarcasm. Moreover, functioning, neurocognition, disorganization and SC had a linear relationship across the three clusters, while positive symptoms were significantly lower in patients with unimpaired SC as compared with patients with impaired and very impaired SC. On the other hand, negative symptoms were highest in patients with impaired levels of SC. CONCLUSIONS If replicated, the identification of such subtypes in clinical practice may help in tailoring rehabilitation efforts to the person's strengths to gain more benefit to the person.

Abstract
IntroductionCurrent research suggested that avolition in patients with schizophrenia (SCZ) is not due to a deficit of hedonic experience, but to a poor ability to translate pleasurable experiences into motivational states. In line with this hypothesis, several evidences showed a preserved hedonic experience, even in the presence of severe trait anhedonia and avolition in SCZ.ObjectivesTo test the hypothesis that memory dysfunction, generally found in SCZ, could lead to inaccurate representations of emotional experiences and interfere with translation of pleasurable experience in motivation.AimsThe present study was aimed to investigate the relationships between state and trait anhedonia, avolition and cognitive functioning in 35 SCZ.MethodsIn SCZ and matched healthy controls (HC) the Temporal experience of Pleasure (TEPS) and Chapman's scales were used to assess trait anhedonia. The MID task was used to assess in-the-moment hedonic experience. Avolition was measured by the Schedule for the Deficit Syndrome. MATRICS Consensus Cognitive Battery was used to assess cognition.ResultsSCZ did not differ from HC on TEPS or on MID task performance but reported higher scores for trait social anhedonia. Trait social anhedonia was associated with memory dysfunction and showed a correlation with avolition.ConclusionsOur results confirm the disjunction between state and trait anhedonia and demonstrate a relationship of the latter with memory impairment and avolition, suggesting that inaccurate representations of emotional experiences might impede their translation in motivation to act.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionDifficult access and low quality of health care are recognized as factors that may account for the excess deaths widely reported in patients with schizophrenia. As a matter of fact, psychiatrists not always possess adequate competences in the assessment of physical health, while non-psychiatric physicians receive little training in psychiatry and are not prepared to take care of subjects with severe mental illnesses.ObjectivesWe present a comprehensive and systematic algorithm for screening medical comorbidities, conceived to be easy to use for psychiatrists, after a brief training.AimsThe study is aimed to implement an instrument for proper detection and management of physical illnesses in people with schizophrenia.MethodsThe screening protocol, developed by internal medicine specialists, was applied to 15 subjects in two independent assessments, one performed by trainees in psychiatry, after a brief training, and one carried out by one specialist and two trainees in internal medicine. The analysis of the inter-rater reliability was carried out by calculating the Cohen's kappa coefficient and the intraclass correlation coefficient as appropriate.ResultsThe agreement among raters resulted excellent for 61% of items, good for 17%, moderate for 18% and scarce for 4%. The few items showing scarce inter-rater reliability were excluded. The final algorithm is being tested for feasibility in psychiatric settings.ConclusionsThe proposed screening protocol resulted in a suitable tool, showing moderate to excellent inter-rater reliability, that can be used in clinical practice by psychiatrists after a brief training.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionThe inter-relationships of neurocognition, social cognition, residual psychopathology and real-life functioning are poorly understood. A large multicenter study was carried out by the Italian Network for Research on Psychoses to model relationships between neurocognitive deficits, psychopathology and real-life functioning, taking into account the role of functional capacity and social cognition.MethodsA structural equation model was used to investigate direct and indirect effects of neurocognition and psychopathology on real-life functioning. Social cognition and functional capacity were modeled as mediators.ResultsIn 921 patients with schizophrenia, neurocognition had both direct and indirect effects, through functional capacity and social cognition, on real-life functioning. Neurocognition predicted to a large extent social cognition on which depression and disorganization had a modest effect. Social cognition showed a significant direct impact on real-life functioning.ConclusionOur results support a strong link between neurocognition and functional outcome, independent of psychopathology. Social cognition accounted for unique incremental variance in real-life functioning.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
West Nile virus (WNV) is a zoonotic arboviral pathogen transmitted by mosquitoes in a cycle that involves wild birds as reservoir hosts. The virus is responsible for outbreaks of viral encephalitis in humans and horses. In Europe, Culex pipiens (Diptera: Culicidae) is considered to be the main vector of WNV, but other species such as Stegomyia albopicta (=Aedes albopictus) (Diptera: Culicidae) may also act as competent vectors of this virus. Since 2008 human cases of WNV disease have been reported in northeast Italy. In 2011, new areas of southern Italy became involved and a first outbreak of WNV lineage 1 occurred on the island of Sardinia. On the assumption that a potential involvement of St. albopicta in WNV transmission cannot be excluded, and in order to evaluate the competence of this species for the virus, an experimental infection of an St. albopicta laboratory colony, established from mosquitoes collected in Sardinia, was carried out. The results were compared with those obtained in a colony of the main vector Cx. pipiens. The study showed St. albopicta collected on Sardinia to be susceptible to WNV infection, which suggests this Italian mosquito species is able to act as a possible secondary vector, particularly in urban areas where the species reaches high levels of seasonal abundance.

Abstract
BACKGROUND The neurobiological underpinnings of avolition in schizophrenia remain unclear. Most brain imaging research has focused on reward prediction deficit and on ventral striatum dysfunction, but findings are not consistent. In the light of accumulating evidence that both ventral striatum and dorsal caudate play a key role in motivation, we investigated ventral striatum and dorsal caudate activation during processing of reward or loss in patients with schizophrenia. METHOD We used functional magnetic resonance imaging to study brain activation during a Monetary Incentive Delay task in patients with schizophrenia, treated with second-generation antipsychotics only, and in healthy controls (HC). We also assessed the relationships of ventral striatum and dorsal caudate activation with measures of hedonic experience and motivation. RESULTS The whole patient group had lower motivation but comparable hedonic experience and striatal activation than HC. Patients with high avolition scores showed lower dorsal caudate activation than both HC and patients with low avolition scores. A lower dorsal caudate activation was also observed in patients with deficit schizophrenia compared to HC and patients with non-deficit schizophrenia. Dorsal caudate activity during reward anticipation was significantly associated with avolition, but not with anhedonia in the patient group. CONCLUSIONS These findings suggest that avolition in schizophrenia is linked to dorsal caudate hypoactivation.

Abstract
BACKGROUND The Brief Negative Symptom Scale (BNSS) was developed to address the main limitations of the existing scales for the assessment of negative symptoms of schizophrenia. The initial validation of the scale by the group involved in its development demonstrated good convergent and discriminant validity, and a factor structure confirming the two domains of negative symptoms (reduced emotional/verbal expression and anhedonia/asociality/avolition). However, only relatively small samples of patients with schizophrenia were investigated. Further independent validation in large clinical samples might be instrumental to the broad diffusion of the scale in clinical research. METHODS The present study aimed to examine the BNSS inter-rater reliability, convergent/discriminant validity and factor structure in a large Italian sample of outpatients with schizophrenia. RESULTS Our results confirmed the excellent inter-rater reliability of the BNSS (the intraclass correlation coefficient ranged from 0.81 to 0.98 for individual items and was 0.98 for the total score). The convergent validity measures had r values from 0.62 to 0.77, while the divergent validity measures had r values from 0.20 to 0.28 in the main sample (n=912) and in a subsample without clinically significant levels of depression and extrapyramidal symptoms (n=496). The BNSS factor structure was supported in both groups. CONCLUSIONS The study confirms that the BNSS is a promising measure for quantifying negative symptoms of schizophrenia in large multicenter clinical studies.

Abstract
BACKGROUND Studies investigating neurocognitive impairment in subjects with eating disorders (EDs) have reported heterogeneous patterns of impairment and, in some instances, no dysfunction. The present study aimed to define the pattern of neurocognitive impairment in a large sample of bulimia nervosa (BN) patients and to demonstrate that neuroendocrine, personality and clinical characteristics influence neurocognitive performance in BN. METHOD Attention/immediate memory, set shifting, perseveration, conditional and implicit learning were evaluated in 83 untreated female patients with BN and 77 healthy controls (HC). Cortisol and 17β-estradiol plasma levels were assessed. Cloninger's Temperament and Character Inventory - Revised (TCI-R), the Bulimic Investigation Test Edinburgh (BITE) and the Montgomery-Asberg Depression Rating Scale (MADRS) were administered. RESULTS No impairment of cognitive performance was found in subjects with BN compared with HC. Cortisol and 'Self-directedness' were associated with better performance on conditional learning whereas 17β-estradiol had a negative influence on this domain; 'Reward dependence' was associated with worse performance on implicit learning; and depressive symptomatology influenced performance on the Wisconsin Card Sorting Test (WCST) negatively. CONCLUSIONS No cognitive impairment was found in untreated patients with BN. Neuroendocrine, personality and clinical variables do influence neurocognitive functioning and might explain discrepancies in literature findings.

Abstract
IntroductionIt has been hypothesized that cognitive remediation with adjunctive psychiatric rehabilitation would be associated with greater improvements in functional outcome than standalone treatment approaches (1).Moving from these observations our group designed an individualized rehabilitation program including a computerized cognitive training (CCT) and social skills training (SST), which showed promising results (2).A critical evaluation of recent studies examining standalone and combined treatment approaches included the understanding of the differential impact of the two approaches among crucial areas for future research (3).ObjectivesThe present study compared the effects of CCT and SST on several indices of outcome in psychotic patients. Fifty-eight patients with schizophrenia or schizoaffective disorder were randomly assigned to one of two treatment groups: CCT or SST. Changes in cognitive, psychopathological and psychosocial indices after 6 and 12 months were compared between the two groups.ResultsAfter both 6 and 12 months, an improvement of psychosocial indices was observed in both groups, while cognitive functions improved only after CCT; the improvement of psychopathological indices, observed in both groups, was greater in the CCT group.ConclusionsOur findings suggest that CCT is associated with a greater impact than SST on different indices of outcome in psychotic patients. Future research should focus on possible synergistic effects of cognitive remediation and social skills training on functional outcome.

Abstract
A brief review of the arboviruses isolated In Italy is presented and discussed. Some of the Arboviruses considered in this paper are endemic in the country and are transmitted by arthropods that play actually a role of vectors, (sand flyes, hard ticks and mosquitoes); other arboviruses, sporadically isolated, are potential agents of emerging human or zoonotic diseases.

Abstract
The P3 is probably the most well known component of the brain event-related potentials (ERPs). Using a three-tone oddball paradigm two different components can be identified: the P3b elicited by rare target stimuli and the P3a elicited by the presentation of rare non-target stimuli. Although the two components may partially overlap in time and space, they have a different scalp topography suggesting different neural generators. The present study is aimed at defining the scalp topography of the two P3 components by means of reference-independent methods and identifying their electrical cortical generators by using the low-resolution electromagnetic tomography (LORETA). ERPs were recorded during a three-tone oddball task in 32 healthy, right-handed university students. The scalp topography of the P3 components was assessed by means of the brain electrical microstates technique and their cortical sources were evaluated by LORETA. P3a and P3b showed different scalp topography and cortical sources. The P3a electrical field had a more anterior distribution as compared to the P3b and its generators were localized in cingulate, frontal and right parietal areas. P3b sources included bilateral frontal, parietal, limbic, cingulate and temporo-occipital regions. Differences in scalp topography and cortical sources suggest that the two components reflect different neural processes. Our findings on cortical generators are in line with the hypothesis that P3a reflects the automatic allocation of attention, while P3b is related to the effortful processing of task-relevant events.

Abstract
OBJECTIVE Cognitive impairment, more often involving memory and/or executive functions, has been reported in obsessive-compulsive (OC) patients. The present study aimed at: i) replicating, in an independent sample, previous findings by our group showing neurocognitive slowness limited to executive tasks; ii) assessing the influence of deficit in general cognitive abilities on executive dysfunction. METHOD A comprehensive neuropsychological battery was administered to 30 drug-free OC patients and 30 healthy controls. RESULTS Obsessive-compulsive patients performed worse on visuospatial tests, were slower on executive tasks, and performed worse on the Wisconsin Card Sorting Test. After covarying for Wechsler Adult Intelligence Scale-Revised performance Intellectual Quotient, a lesser degree of executive dysfunction was observed. CONCLUSION Obsessive-compulsive patients exhibit an impairment of executive functions, especially when tasks also require visuospatial abilities. The impairment might reflect a hyperactivity of the executive control.

Abstract
Evidence has been provided that high frequency oscillations within the gamma band reflect mechanisms of cortical integration. In the light of recently proposed pathophysiological models of schizophrenia, suggesting a disturbance of the functional connectivity within distributed neural networks, it has been hypothesized that abnormalities in the gamma band underlie perceptual and cognitive dysfunctions in patients with schizophrenia. In the present study we investigated evoked and induced 40-Hz gamma power as well as frontoparietal and frontotemporal event-related coherence in patients with deficit and nondeficit schizophrenia and in matched healthy controls. In patients, correlations between gamma oscillations and psychopathological dimensions were also investigated. A reduction of both induced gamma power and event-related coherence was observed in patients with nondeficit schizophrenia, but not in those with deficit schizophrenia. Our findings support the hypothesis that deficit and nondeficit schizophrenia represent separate disease entities, suggesting the presence of a poor integration of the neuronal activity within distributed neural network only in the subgroup of schizophrenic patients without primary and persistent negative symptoms. Associations between an excess of gamma oscillations and psychopathological dimensions were observed, suggesting that abnormal thoughts, behaviors and perceptions might be related to the formation of inappropriate neural connections.
