Abstract
Frequency characteristics of cortical biopotentials and their spatio-temporal interrelations were analyzed with a digital computer during creation of a posture dominant through chronic polarization of the right cerebral hemisphere premotor area in rabbits. The power spectrum within the .delta. range increased with increase of coherence between the biopotentials of the same frequency range. The changes in the electrical activity occurred on the 2nd day in the backgroud EEG when the animal was put into the experimental surroundings. Spectral-correlation characteristics correspond to the parameters of the previous day during the creation of the dominant. The process of memory and specifically the high value of the summary electrical activity are discussed.
