20 patients suffering from chronic alcoholism and 10 healthy, righthanded persons with normal sight were examined. Alcoholics were trained to elaborate a temporary connection by means of unrecognized significant word "vodka" related to their dominant motivation. The amplitude of the late positive response P300 was greater and its latency was shorter(More)
Average evoked potentials (AEP) were recorded in practically healthy subjects to "meaningless" figures and letters, presented to different halves of the visual field. Analysis of the amplitudes of AEP late components to verbal and non-verbal stimuli reveals hemispheric asymmetry. A higher amplitude of the late positive evoked response (P300) to a "direct"(More)
In healthy adult subjects recognition was studied of geometrical figures presented unilaterally, and of separate letters presented unilaterally and dichoptically to the right and left visual fields. At near-threshold exposition, separate letters are better recognized in the right visual field, than in the left one, regardless of the method of presentation.(More)
Recognition of short time intervals (10, 60, and 180 ms) between visual stimuli presented to the left or right hemisphere was studied in adult healthy people. The interval of 180 ms is recognized better than that of 10 or 60 ms. Learning with repeated tests with 180 ms intervals proceeds better than that with short intervals. The predominance of the left(More)
By means of backward masking, the time of perception of letter stimuli presented to the left and right visual fields, was determined in practically healthy persons who were given different doses of alcohol, and in patients with chronic alcoholism. Evoked electrical activity to the same stimuli was recorded in identical conditions. A small dose of alcohol(More)
The dynamics of the cortical evoked activity in the process of learning of time microintervals (10, 60 and 180 ms) discrimination was studied in healthy adults. Feedback stimulus visually informing of the real correlations of the differentiated pauses facilitates the discrimination. The factor of the visual field does not affect the estimation of brief time(More)
