[Reorganization of human evoked potentials during automatization of motor reactions].
Evoked electrocortical activity appearing during rhythmic stimulation and its correlation with the level of expectancy of the signal next in turn (expressed in values of reaction time), were studied in nine grown up subjects. Reorganization of auditory evoked potentials (EPs), mostly expressed during reactions preceding the stimulus or coinciding with it occurs at motor responses to rhythmical stimuli. The character of correlation between EPs and perception is satisfactorily explained by a cyclic model of the sensory information processing. Adaptive behaviour is provided by the cyclic processes promoting engrams formation and adequate pretuning to probable events.
