[EEG activity of symmetrical points of the cerebral cortex during unilateral cooling of the temporal neocortex in cats].
A study of ten alert cats has shown that inactivation with cold of the temporal neocortex elicits a sharp drop in EEG activity in all the examined points of the homonymous hemisphere, which actually points to a temporary switching off of its function. At the same time a unilateral switching off of the temporal area brings about an increase in EEG activity of the contralateral hemisphere. Functional asymmetry sets in not only in the system of the auditory analyser, but also in other sensory systems. Systematic cold switching off of the temporal cortex in one hemisphere results in a reduced contrast in the EEG of the brain symmetrical regions.
