[A coherence analysis of the electrical activity of the rabbit brain during a shift in the dominants].
Coherence between the electrical activity in the sensorimotor (forelimb and blinking centers) and visual cortical areas, as well as VPL of the left and right thalamus was studied during creation of the motor defensive dominant by the serial electrical forelimb stimulation against the background of the blinking dominant (produced by the serial eye stimulation with an air stream). An increase in EEG coherence in the delta-range was observed in the structures which realized the defensive reflex. Formation of the latent defensive dominant destroyed the typical for the dominant state relationships of potentials in the cortical structures responsible for realization of the blinking reflex.
