Název v původním jazyce

Electrical brain responses evoked by human faces in acute psychosis

Popis výsledku v původním jazyce

Patients with schizophrenia are known to have behavioral deficits in recognizing faces and facial expressions. However, the ability to process simple visual stimuli appears to be intact in first-episode psychosis. The aim of this study was to examine complex visual processing, especially the event-related potentials (ERPs) elicited by human faces, in early psychosis. Never-medicated patients in acute psychosis (n = 18) were compared with healthy controls (n = 19). Photographs of human faces were presented in a classic oddball paradigm requiring a motor response to a smiling face. Cerebral sources of ERPs were analyzed of the averaged responses, using minimum norm estimates, and dipole models. Face-sensitive response at 145 ms after the face stimuli wasof significantly higher amplitude in our never-medicated patients, and the activity distribution between the groups was clearly different.
