Abstract

Evoked cortical activity in response to acoustic stimuli (oddball paradigm) was studied in patients with different paranoid disorders. The analysis covered the N150 negative wave and positive complex P300. In patients with paranoid schizophrenia and paranoid form of involutional psychosis cortical responses to the stimuli and cortex effects were not recorded. Such cognitive deficiency is believed to be typical for schizophrenia.

Abstract

In the excitable psychopaths and persons with some psychopathic traits (Leonard's "accentuated personality") the study was made of a cognitive function of discriminating microintervals and event-related potentials to visual stimuli. A qualitative difference in the accomplishment of the cognitive task between the two groups was found. Disturbances of the cognitive function, learning deficiency and reduction of the P300 wave provide grounds for referring this ""antisocial personality disorder" to pathology of the limbic system of the brain.

Abstract

Two groups of schizophrenics with negative and positive syndromes were studied by registering cortical evoked potentials in response to acoustic stimuli of different meaning (odd-ball paradigm). Disfunction of selective attention is related to the impaired ability to differentiate relevant and irrelevant information. Disturbances of information selection were more pronounced in the patients with paranoid schizophrenia.
