Neural Mechanisms for Behavioral Differences on Visual Integration in Schizophrenia

Cognitive functions like planning, reasoning, inhibiting as well as working memory are disrupted in schizophrenia. Cognitive impairments precede psychotic symptoms, and findings have consistently shown deficits in visual integration. Specifically, the visual integration disturbance in schizophrenia pertains to both an impaired basic visual processing system as well as reduced feedback from visual attention regions that should actually be amplifying relevant visual representations in contrast to irrelevant information. The goal of this project is to identify differences and establish a baseline in the neuronal oscillations for a visual integration task in individuals with schizophrenia and healthy participants using electroencephalograms (EEGs).
