[Descending modulation of monosynaptic reflexes after traumatic injury of the cat spinal cord]

Studies of the descending modulation of monosynaptic reflex responses have revealed that electrical stimulation of dorsolateral, ventrolateral and ventral funiculi in C2 facilitated and suppressed test responses of intact animals, but evoked only suppression of spinal reflexes after injury of the spinal cord. The obtained data have shown that descending pathways which transmit facilitatory influences are more vulnerable to injury of the spinal cord.
