[Change in the feedback inhibition of monosynaptic spinal cord reflexes following removal of the anterior lobe of the cerebellum in cats].
In acute experiments on cats monosynaptic extensor and flexor reflexes and their recurrent inhibition were recorded from a L7 ventral root filament before and after removal of the anterior lobe of the cerebellum. Removal of the anterior lobe reduced the amplitude of monosynaptic extensor and flexor responses and at the same time decreased the level of recurrent inhibition of extensor reflexes and increased that of flexor reflexes. On the basis of these data it is suggested that the background control form the anterior lobe of the level of recurrent inhibition is one of the possible mechanisms participating in the cerebellar control of spinal motoneurons.
