title: [The characteristics of the reproduction of time intervals and the individual structure of the EEG in man].
abstract: The perception of time by humans was studied by the method of time reproduction. The EEG was recorded in Os, Od, Cs, Cd, Fs and Fd derivations. The relative EEG spectral power was determined in the delta-1, delta-2, theta, alpha, beta-1, and beta-2 ranges. All the subjects were divided in two groups: I--those who reproduced time-intervals with a delay, and II--those who were ahead in their reproduction. The spectral power of the delta-rhythm was significantly lower and that of the beta-rhythm higher in the subjects of the I than of the II group. In subjects of the II group total power of the beta range (beta-1 + beta-2) was significantly less than that in the delta-range (delta-1 + delta-2). This ratio was inverse in subjects of the I group. The described relationships were expressed both in the background EEG and during functional loads in all the studied derivations.
