Publications related to Visual backward masking and the schizophrenia spectrum: EEG correlates

Michael Herzog, Ophélie Gladys Favrod, Patricia Figueiredo, Janir Nuno Ramos Antunes Da Cruz, Phillip Ready Johnston

When a task-relevant stimulus is presented for a brief duration or with low contrast, neural enhancement is needed to boost the weak responses to the target. Otherwise, the stimulus goes unnoticed, which is the default when the stimulus is task-irrelevant. ...

Electrophysiological correlates of visual backward masking in patients with major depressive disorder

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

Depression and schizophrenia are two psychiatric diseases with high co-morbidity. For this reason, it is important to find sensitive endophenotypes, which may disentangle the two disorders. The Shine-Through paradigm, a visual backward masking task, is a p ...

EEG microstates in schizophrenia: a candidate endophenotype

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

Objective: Electroencephalogram (EEG) microstates are on-going scalp potential configurations that remain stable for around 80 ms. Abnormal temporal dynamics of specific classes of microstates have been suggested as a potential endophenotype for schizophre ...

(Visual) Endophenotypes in schizophrenia research

Michael Herzog, Maya Roinishvili, Ophélie Gladys Favrod, Albulena Jashari-Shaqiri

Objective: Schizophrenia is a heterogeneous disease strongly influenced by genetic disposition. However, genetic studies have shown that each single nucleotide polymorphism (SNP) contributes very little to the disease. For this reason, endophenotypes, loca ...

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 ...

Sensorimotor Induction of Auditory Misattribution in Psychosis is Linked to Neural Disconnectivity

Olaf Blanke, Andrea Serino, Alessandra Griffa, Patric Hagmann, Kim Do, Roy Salomon, Giulio Rognini, Silvia Marchesotti, Pierre Progin

Background: Schneiderian first rank symptoms (FRS) are characterized by a diminished demarcation of self-other boundaries, causing misattribution of self-generated thoughts and actions to external sources. We have shown that introducing sensorimotor predic ...

Cortical morphology development in patients with 22q11.2 deletion syndrome at ultra-high risk of psychosis

Maude Schneider, Marie Schaer, Daniela Maria Zöller, Maria Carmela Padula

Background. Patients with 22q11.2 deletion syndrome (22q11DS) present a high risk of developing psychosis. While clinical and cognitive predictors for the conversion towards a full-blown psychotic disorder are well defined and largely used in practice, neu ...

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 ...

Visual backward masking in siblings of schizophrenia patients: evidence for a compensation mechanism

Michael Herzog, Maya Roinishvili, Patricia Figueiredo

Visual backward masking (VBM) is a very sensitive endophenotype of schizophrenia. Masking deficits are highly correlated with reduced EEG amplitudes. In VBM, a target stimulus is followed by a mask, which decreases performance on the target. Here, we inves ...
