Abstract
OBJECTIVES Schizotypy relates to rejection sensitivity (anxiety reflecting an expectancy of social exclusion) and neuroticism (excessive evaluation of negative emotions). Positive schizotypy (e.g., perceptual aberrations and odd beliefs) and negative schizotypy (e.g., social and physical anhedonia) could relate to altered attention to rejection because of neuroticism. METHODS Forty-one healthy individuals were assessed on positive and negative schizotypy and neuroticism, and event-related potentials during rejecting, accepting and neutral scenes. Participants were categorised into high, moderate and low neuroticism groups. Using temporo-spatial principal components analyses, P200 (peak latency = 290 ms) and P300 amplitudes (peak latency = 390 ms) were measured, reflecting mobilisation of attention and early attention, respectively. RESULTS Scalp-level and cortical source analysis revealed elevated fronto-parietal N300/P300 amplitude and P200-related dorsal anterior cingulate current density during rejection than acceptance/neutral scenes. Positive schizotypy related inversely to parietal P200 amplitude during rejection. Negative schizotypy related positively to P200 middle occipital current density. Negative schizotypy related positively to parietal P300, where the association was stronger in high and moderate, than low, neuroticism groups. CONCLUSIONS Positive and negative schizotypy relate divergently to attention to rejection. Positive schizotypy attenuates, but negative schizotypy increases rejection-related mobilisation of attention. Negative schizotypy increases early attention to rejection partly due to elevated neuroticism.

Do schizophrenia patients with low P50-suppression report more perceptual anomalies with the sensory gating inventory? Schizophr Res 2014; 157:157-62. [PMID: 24893905 DOI: 10.1016/j.schres.2014.05.013] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/01/2014] [Revised: 04/12/2014] [Accepted: 05/05/2014] [Indexed: 01/23/2023]
Abstract
BACKGROUND P50 amplitude changes in dual click conditioning-testing procedure might be a neurophysiological marker of deficient sensory gating in schizophrenia. However, the relationship between abnormalities in the neurophysiological and phenomenological dimensions of sensory gating in schizophrenia remains unclear. The aim of the present study was to determine if patients with low P50-suppression (below 50%) report more perceptual anomalies. METHODS Three groups were compared: twenty-nine schizophrenia patients with high P50-suppression (above 50% amplitude suppression), twenty-three schizophrenia patients with low P50-suppression (below 50%) and twenty-six healthy subjects. The Sensory Gating Inventory (SGI), a four-factor self-report questionnaire, was used to measure perceptual anomalies related to sensory gating. A comparison of demographic and clinical data was also carried out. RESULTS Patients with low P50-suppression presented: i) significantly higher scores on the SGI (for the overall SGI score and for each of the 4 factors) and ii) significantly larger P50 amplitude at the second click, than both patients with high P50-suppression and healthy subjects. There were no group differences in the most of demographic and clinical data. DISCUSSION The finding offers support for conceptual models wherein abnormal neurophysiologic responses to repetitive stimuli give rise to clinically relevant perceptions of being inundated and overwhelmed by external sensory stimuli. Further studies are needed to explore the contributions of clinical symptoms, medication and neuropsychological functions to the relationship between P50-suppression and the SGI, and the role of sensory "gating in" versus "gating out".

Abstract
It is proposed an historical approach to concepts leading to the development of operational paradigms for measuring objectives neurophysiological endophenotypes. It is hypothesized that psychiatric interest for paradigms measuring Event-Related Potential (ERP) come from Bleuler (1911) and McGhie and Chapman (1961) phenomenological and clinical descriptions. They noted, first that patients with schizophrenia generally feel as if they are being flooded by an overwhelming mass of sensory input combined with a heightened sensory perception, second that they were distractible to irrelevant sensory stimuli. These subjective abnormalities may be related, first to inability to filter incongruent information measured in a double click paradigm by a deficit in P50 amplitude gating, and second to an inability to select a stimulus of interest measured in the oddball paradigm by a deficit in P300 amplitude. The analysis of these P50 and P300 ERP in cohorts of patients with schizophrenia found most of Gottesman endophenotype criteria. P50 and P300 ERP are therefore relevant neurophysiological endophenotypes. However, from a clinical point of view, these endophenotypes lack specificity. The hypothesis of this article leads us to formulate ways of research. It is shown the value of combining objective neurophysiological measures with subjective measures using self-administered questionnaires ("offline") or psychophysiological tests ("online") to develop rigorous neurophysiological experimental paradigms especially as clinical observations of their origins are not forgotten.
