Abstract

Evoked potential data in schizophrenia suggest the existence of functional disorders in different stages of information processing. Impairment in gating of P50 component and a diminished amplitude of Mismatch Negativity (MMN) suggest disordered processing at the level of primary auditory cortex. In several investigations diminished amplitude of P300 component was reported, which points to the moment of problem solving. There are also data on diminished amplitude of N400, which is connected with semantic processing.
