title: [Excitability of the senso-motor cortex and red nucleus of rabbits with different levels of cortical potential spatial synchronization].
abstract: The motor reaction of the rabbit to the threshold electrical stimulation of the sensomotor cortex and red nucleus was studied to determine excitability of these structures. Under conditions of the computer-controlled experiment the excitability of the two structures was compardd for situations characterized by different levels of cortical potential correlation. An increase in the spatial synchronization of the cortical potentials is shown to be accompanied by intensification in excitability of the sensomotor cortex and red nucleus. This intensification seems to be one of possible neurophysiological mechanisms of the probability increase for the effector reaction to sensory stimuli when the cortical spatial synchronization rises.
