[Functional reorganization in the system of corticotectal connections after unilateral deafferentation of the cortex].
The responses of the cat's collicular neurons to direct stimulation (DCR) of contralateral neocortex were studied in various periods after unilateral dissection of cortico-subcortical connections. The data obtained suggest that, in intact cat's brain, during early hours of postoperative period, and within 1-2 years after the operation, functional specifics of contralateral motor and sensory projections to superior colliculus played a major part in determining basic features of compensatory shifts of the impulse activity of collicular neurons.
