title: [Spectral correlation analysis of the electrical activity of rabbit neocortex during creation of a postural dominant in a chronic experiment].
abstract: Frequency characteristics of cortical biopotentials and their spatio-temporal interrelations were analysed by means of a digital computer, during creation in chronic experiment of a posture dominant through polarization of the premotor area of the right cerebral hemisphere in rabbits. In the course of experiments with the dominant, the power spectrum within the delta-range increased with the increase of coherence between the biopotentials within the same frequency range. The changes in the electrical activity observed in the experiment with the dominant, occured on the second day in the background EEGs with putting of the animal into the experimental surroundings. Spectral-correlation characteristics corresponded to the parameters, obtained on the previous experimental day with the creation of the dominant. The obtained data are considered as relevant to the phenomenon of memory and point to a high informativeness of the summary electrical activity.
