Makhin S. Time interval production: analysis of EEG and evoked brain potentials.

Thesis studies the interrelation between the qualities of time reflection by man, the indicators of neurodynamics by healthy and mentally ill subjects, and properties of rhythmical EEG activity and evoked brain potentials. There is discovered that individual time interval perception by healthy subjects differs from that by mentally ill ones. A distortion of time perception takes place as a result of neural plasticity disorder, present in mentally ill subjects. The situation of temporal self-regulation on the basis of authentic outer reference point provides negative correlation between alpha-frequency of mostly left hemisphere and duration of produced interval. The situation of "natural" time production (without reference points) gives such the role to beta-rhythm. People, inclined to overestimate time duration of 20 seconds have larger amplitudes of RP, PSN and P300. The RP dynamics is different in series with informative and non-informative feedback.
