title: [The dynamics of the dominant alpha-rhythm frequency in the perception and reproduction of time intervals].
abstract: Dependence of the dominant alpha frequency on the processes of perception and subsequent reproduction of time intervals by rhythmic hand pressing was analysed. Two groups of subjects were separated, which demonstrated either an increase (I) or a decrease (II) in the dominant alpha frequency after the transition from perception to reproduction. In the I group 83% of the subjects reproduced time intervals with a delay. In the II group reproduction in advance was observed in 75% of the subjects. The dynamics of the dominant alpha frequency probably reflects formation of the optimal functional state underlying the individual level of activation and properties of the higher nervous activity in the subjects from both groups.
