(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 ...

Across cultures, people associate colours with emotions. Here, we test the hypothesis that one driver of this cross-modal correspondence is the physical environment we live in. We focus on a prime example - the association of yellow with joy, - which conce ...

Schizophrenia (SCZ) patients show deficits in many domains, including cognition and perception. However, results are often mixed. One reason for mixed results may be differences in medication. Very little is known about the role of medication in visual pro ...

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 ...

Introduction: Electroencephalogram (EEG) microstates are on-going scalp potential configurations that remain stable for around 80 ms (1). Four recurrent and dominant classes of microstates (labeled A-D) are observed in resting-state EEG, explaining around ...

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 ...

Objective: In visual backward masking, a target is followed by a mask, which deteriorates performance on the target. Masking is a very sensitive endophenotype for schizophrenia. Patients and their siblings (to a lesser extent) show strong performance defic ...

Visual masking deficits in schizophrenia: A view into the genetics of the disease through an endophenotype

Michael Herzog, Jacques Fellay, Maya Roinishvili, Flavia Aurelia Shoko Hodel

Schizophrenia is a chronic disorder determined by a complex mix of genetic and environmental factors. To better understand the contributions of human genetic variation to schizophrenia, we performed a genome-wide association study of a validated endophenot ...

Perception of visual illusions is intact in schizophrenia

Michael Herzog, Maya Roinishvili, Lukasz Grzeczkowski, Fred Mast

There seems to be no common factor for visual perception because performance levels in many visual tasks correlate only weakly with each other. Similar results were found with visual illusions. However, one may expect common visual factors for individuals ...

Is the perception of illusions abnormal in schizophrenia?

Michael Herzog, Maya Roinishvili, Lukasz Grzeczkowski, Fred Mast

There seems to be no common factor for visual perception, i.e., performance in visual tasks correlates only weakly with each other. Similar results were found with visual illusions. One may expect common visual factors for individuals suffering from pathol ...
