[The role of feedback in the dynamics of functional asymmetry of brain hemispheres in man].

Reaction time, number of correct evaluations of time microintervals, and P300 wave were studied in healthy adult subjects. The role is shown of feedback stimuli in training of a subject to discriminate short intervals and in changes of interhemispheric functional relations. These relations change in the course of training as a result of lateralized activation of the left hemisphere. Training with informative feedback is more efficient in the left hemisphere. The right hemisphere in lesser extent than the left one is subject to correcting influence of the feedback. In this sense the former is more autonomous.
