[Structural-functional reorganization of the brain after sequential removal of the regions of the motor cortex in cats and dogs].

It was shown in experiments on cats and dogs that the greater the mass of removed motor cortex on one side, the longer the time for restoring lost motor functions. Repeated ablations of the areas adjacent with the previously extirpated cortical zone after the restoration of motor functions, bring about the recurrence of the same disturbances. However the period of restoration after each repeated extirpation is perceptibly shorter. This means that repeated extirpations of cortical areas result in the activation of the mechanisms directed at the reorganization of the brain sensorimotor functions as a new integral system and providing for normalization of the motor functions.
