title: [Psychophysiological characteristics of visual perception in patients with schizophrenia during polarization of the occipital and frontal cortices].
abstract: Purposeful change of the functional status of the occipital and frontal cortex in relation to distinguishing visual stimuli shows that one of the signs indicative of schizophrenia is impairment of the active component of the regulatory mechanism of perception mediating the psychological orientation toward the recognition of meaningful signals and related to functions of the frontal cortex. Analysis of the alterations in the index of importance (serving as a quantitative parameter of changes in the psychological orientation in cases of shifts of the frontal cortex status) have demonstrated that in schizophrenics, unlike in healthy subjects, there is no relationship between changes in the frontal cortex potential and regulation of the critical sphere of perception.
