EEG signatures of schizophrenia: visual backward masking and microstates

Schizophrenia is a complex and devastating mental disorder that influences how one behaves, feels, and thinks. It affects a little less than 1 % of the world population and it is understood to be partly genetically mediated. Several genetic risk factors of ...

Visual masking and schizophrenia: enhancement deficit 200 ms after stimulus onset

Michael Herzog, Maya Roinishvili, Ophélie Gladys Favrod, Janir Nuno Ramos Antunes Da Cruz

Masking is strongly deteriorated in schizophrenia patients and to a lesser extent in their healthy relatives. For this reason, masking is a good endophenotype. Here, we show the EEG correlates of masking across the schizophrenia continuum in order to tackl ...

Audio-visual sensory deprivation degrades visuo-tactile peri-personal space

Olaf Blanke, Hervé Lissek, Andrea Serino, Jean-Paul Noel, Hyeongdong Park, Isabella Maria Pasqualini

Self-perception is scaffolded upon the integration of multisensory cues on the body, the space surrounding the body (i.e., the peri-personal space; PPS), and from within the body. We asked whether reducing information available from external space would ch ...

Visual backward masking and the schizophrenia spectrum: EEG correlates

Michael Herzog, Maya Roinishvili, Ophélie Gladys Favrod

Schizophrenia is a heterogeneous disease strongly influenced by genetic factors. We have previously shown that visual backward masking (VBM) is a very sensitive endophenotype of schizophrenia (Chkonia et al., 2010). Importantly, not only patients but also ...

Neural correlates of visual backward masking in psychosis

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

In visual backward masking (VBM), a target is followed by a mask, which deteriorates performance on the target. Schizophrenia and first episodes patients show strong behavioral deficits, reflected in strongly reduced amplitudes of the EEG as compared to co ...

Electrophysiological correlates of visual backward masking in high schizotypic personality traits participants

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

Visual backward masking is strongly deteriorated in patients with schizophrenia. Masking deficits are associated with strongly reduced amplitudes of the global field power in the EEG. Healthy participants who scored high in cognitive disorganization (a sch ...

Electrophysiological Correlates of Visual Backward Masking in Schizotypy

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

Visual deficits are well documented in schizophrenia. For example, a Vernier is followed by a blank inter-stimulus interval (ISI) and then a grating mask. Observers indicate the direction of the Vernier offset (left vs right). Patients need ISIs that are 1 ...

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 ...

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 ...
