title: [States of preadjustment under conditions of prolonged activation according to evoked potential findings in schizophrenic patients].
abstract: The paper deals with a psychophysiological study of the states of disposition, expectation with the aid of the method of evoked potentials as one of the indices of peculiarities in activation processes in schizophrenic patients in conditions of active senso-motor activity. The study demonstrated significant differences in the schizophrenic patients in EP changes of cerebral cortex antecentral zones in situations of mental activity associated with expectation, active disposition. Moreover, in conditions of long-term stable activation schizophrenic patients show differences from normals by a character of dynamics of EP changes in the frontal brain areas, as the tension increases. The obtained data can testify to the fact that the given trend of psychophysiological studies may serve as an aspect of search and analysis of factors that are the basis of changes in a selective form of activation in schizophrenia.
