[Functional interaction between the parietal and motor regions of the cerebral cortex].

The role of interaction of parietal and motor nonprojectional areas in cortical integration was studied in acute experiments on cats. Their regulatory modal-nonspecific complex interaction including both the inhibitory and facilitating effects and characterized by the pulsatory aperiodic type of the progress was elucidated. A stronger influence of the parietal area on the motor as compared to that of the motor on the parietal area was recorded, with this influence being important for the motor integrative and trigger function. Interrelations of these areas differed from those between the parietal area and the projectional ones as well as from the latters relationships. These cortical formations demonstrate only mutual facilitating and tonic effect, their functional significance conditioning not only modal-specific or nonspecific influence type, but also a different role in mutual sensory supply.
