- Аннотация: By means of histograms of cross- and autocorrelation plotting the interaction of visual and sensorimotor neocortex neurons was studied before and after stimulation of some medial hypothalamic nucleus. The stimulation was provided by packages of bipolar impulses with frequency of 100 Hz and current value of 50-200 mcA from the bipolar electrodes and resulted in appearance of avoidance reactions to stimulation place at rabbits' free behavior. After stimulation as compared with calm wakefulness the number of pairs of neurons with correlated activity was increased by 45%, the discharges of sensorimotor neurons forestalled the discharges of the visual ones for up to 120 ms, the frequency of periodicity of correlated discharges was basically in the theta-range. By means of comparison the interaction of neurons after stimulation of medial hypothalamus and midbrain reticular formation and in intersignal interval during defensive conditioning the conclusion was made about manifestation of defensive motivation in definite indices of cortical neurons interaction during tonic conditioned reflex.
