Visual impairments in schizophrenia

Michael Herzog, Maya Roinishvili, Albulena Jashari-Shaqiri

The obvious symptoms of schizophrenia are hallucinations, delusions, and cognitive dysfunctions. However, schizophrenia patients have many other abnormalities, including visual impairments. Visual paradigms are versatile tools of schizophrenia research bec ...

Higher N1 responses in relatives of schizophrenia patients than controls in visual backward masking

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

Association for Research in Vision and Ophthalmology2016

Gender differences in visual perception

Michael Herzog, Maya Roinishvili, Guillaume Sierro, Christine Mohr, Albulena Jashari-Shaqiri

Electrophysiological correlates of backward masking in students scoring high in cognitive disorganization

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

Endophenotypes of schizophrenia: electrophysiological correlates of first episode patients

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

Schizophrenia is a heterogeneous disorder and among other symptoms, patients have important visual impairments. Visual paradigms are therefore important tools to investigate the mechanisms of schizophrenia. During the last period of the NCCR, we have chara ...

Schizophrenia patients and 22q11.2 deletion syndrome adolescents at risk express the same deviant patterns of resting state EEG microstates: A candidate endophenotype of schizophrenia

Dimitri Nestor Alice Van De Ville, Michael Herzog, Fikret Isik Karahanoglu, Maya Roinishvili, Maude Schneider

Schizophrenia is a complex psychiatric disorder and many of the factors contributing to its pathogenesis are poorly understood. In addition, identifying reliable neurophysiological markers would improve diagnosis and early identification of this disease. T ...

Does chronic nicotine consumption influence visual backward masking in schizophrenia and schizotypy?

Michael Herzog, Maya Roinishvili, Guillaume Sierro, Christine Mohr, Albulena Jashari-Shaqiri

Nicotine consumption is higher for people within the schizophrenia spectrum compared to controls. This observation supports the self-medication hypothesis, that nicotine relives symptoms in, for example, schizophrenia patients. We tested whether performanc ...

Crowding, grouping, and gain control in schizophrenia

Michael Herzog, Maya Roinishvili, Albulena Jashari-Shaqiri

isual paradigms are versatile tools to investigate the pathophysiology of schizophrenia. Contextual modulation refers to a class of paradigms where a target is flanked by neighbouring elements, which either deteriorate or facilitate target perception. It i ...

What crowding tells about schizophrenia

Michael Herzog, Maya Roinishvili, Albulena Jashari-Shaqiri

Visual paradigms are versatile tools to investigate the pathophysiology of schizophrenia. Contextual modulation refers to a class of paradigms where a target is flanked by neighboring elements, which either deteriorate or facilitate target perception. It i ...

Schizophrenia and visual backward masking: a general deficit of target enhancement

Michael Herzog, Maya Roinishvili

The obvious symptoms of schizophrenia are of cognitive and psychopathological nature. However, schizophrenia affects also visual processing which becomes particularly evident when stimuli are presented for short durations and are followed by a masking stim ...

Electrophysiological Evidence for Ventral Stream Deficits in Schizophrenia Patients

Michael Herzog, Gijs Plomp, Maya Roinishvili

Schizophrenic patients suffer from many deficits including visual, attentional, and cognitive ones. Visual deficits are of particular interest because they are at the fore-end of information processing and can provide clear examples of interactions between ...

Visual masking deficits in healthy and schizophrenic women

Michael Herzog, Maya Roinishvili

Schizophrenic patients have serious visual masking deficits which are likely related to the genetic underpinnings of the disease because also unaffected relatives of the patients show masking deficits. We presented a left/right offset vernier followed by a ...

Association of the Nicotinic Receptor α7 Subunit Gene (CHRNA7) with Schizophrenia and Visual Backward Masking

Michael Herzog, Maya Roinishvili

Patients with functional psychoses show similar visual backward masking deficits

Michael Herzog, Maya Roinishvili

Recent genetic, behavioral, and clinical studies suggest that functional psychoses (schizophrenia, bipolar disorder, schizoaffective disorder), previously thought to be distinct from each other, may belong to one continuum. The shine-through masking paradi ...

Backward masking reveals different visual processing of schizophrenic and depressive patients

Michael Herzog, Maya Roinishvili

Visual backward masking is a very sensitive tool for studying early visual processing deficits and a reliable endophenotype of schizophrenia. Mental diseases strongly overlap in many aspects, for example, in psychopathology, cognition, and genetics. Here, ...

Combining vernier acuity and visual backward masking as a sensitive test for visual temporal deficits in aging research

Michael Herzog, Maya Roinishvili

Performance in many everyday situations slows down when age increases. The causes of slowing down may be found on any stage of information processing. Here, we show that the combination of a vernier acuity task and the shine-through backward masking paradi ...

Elektrophysiologische Korrelate visueller Maskierung bei schizophrenen Patienten

Visual backward masking deficits in schizophrenic patients are associated with polymorphisms in the nicotinic receptor α7 subunit gene (CHRNA7)

Michael Herzog, Maya Roinishvili

Visual backward masking (BM) deficits are often proposed to be trait markers for schizophrenia revealing the genetic underpinnings of the disease. Here, we show that, indeed, masking deficits in the shine-through effect are associated with polymorphisms in ...

First-order relatives of schizophrenic patients are not impaired in the Continuous Performance Test

Michael Herzog, Maya Roinishvili

Sustained attention deficits measured by the Continuous Performance Test (CPT) have been reportedly proposed as an endophenotype of schizophrenia. One requirement for an endophenotype is that unaffected first-order relatives must show deteriorated performa ...
