Electrophysiological correlates of visual backward masking in schizotypy

Michael Herzog, Christine Mohr, Ophélie Gladys Favrod, Guillaume Sierro

Visual backward masking is strongly deteriorated in both schizophrenia and healthy students high as compared to low in cognitive disorganisation (CD; no relationship with positive or negative schizotypy). In patients, this deterioration was also reflected ...

Social deficits induced by peripubertal stress in rats are reversed by resveratrol

Maria del Carmen Sandi Perez, Olivia Zanoletti, Guillaume Poirier

Adolescence is increasingly recognized as a critical period for the development of the social system, through the maturation of social competences and of their underlying neural circuitries. The present study sought to test the utility of resveratrol, a di ...

Endophenotypes of schizophrenia: electrophysiological correlates

Michael Herzog, Christine Mohr, Maya Roinishvili, Ophélie Gladys Favrod

Endophenotypes are of crucial interest for schizophrenia research linking genetic abnormalities to pathology. During the last NCCR period, we have characterized one endophenotype, based on visual backward masking deficits, behaviourally and genetically (po ...

Peripuberty stress leads to abnormal aggression, altered amygdala and orbitofrontal reactivity and increased prefrontal MAOA gene expression

Pierre Magistretti, Maria del Carmen Sandi Perez, Didier Trono, Maria Isabel Cordero Campana, Guillaume Poirier, Anna Claire Groner, Cristina Marquez Vega

Although adverse early life experiences have been found to increase lifetime risk to develop violent behaviors, the neurobiological mechanisms underlying these long-term effects remain unclear. We present a novel animal model for pathological aggression in ...

Visual backward masking deficits are specific to female observers scoring high on cognitive disorganisation

Michael Herzog, Christine Mohr, Guillaume Sierro

Visual backward masking (VBM) deficits are a potential endophenotype of schizophrenia. VBM deficits were found in schizophrenic patients, in their unaffected relatives, and in healthy students scoring high in "cognitive disorganisation" (CD; Cappe et al., ...

Cognitive disorganisation in schizotypy is associated with deterioration in visual backward masking

Michael Herzog, Christine Mohr, Daniela Herzig

To understand the causes of schizophrenia, a search for stable markers (endophenotypes) is ongoing. In previous years, we have shown that the shine-through visual backward masking paradigm meets the most important characteristics of an endophenotype. Here, ...

Visual backward masking deficits in schizotypy

Michael Herzog, Christine Mohr, Daniela Herzig

Background: In visual backward masking, a target is followed by a mask impeding target perception. Visual backward masking is a potential endophenotype for schizophrenia because patients with schizophrenia and also their unaffected relatives show significa ...

Sex moderates the relationship between cognitive disorganisation and visual backward masking: potential implications for an endophenotype of schizophrenia.

Michael Herzog, Christine Mohr, Guillaume Sierro

Schizophrenia is a severe mental disorder that impairs individuals’ life, often chronically and from early adulthood on. There is a search for endophenotypes, i.e. stable markers of the genetic underpinnings of the disease. Visual backward masking (VBM) is ...
