[Periodic changes in primary afferent depolarization during fictitious locomotion in thalamic cats].
Dorsal root and cord dorsum potentials were recorded in lumbar segments L6, L7 during fictitious locomotion of thalamic immobilized cats. Negative waves in the dorsal root potential and respectively positive waves in the cord dorsum potential appeared during periodic discharges in the ankle flexor nerve. The conclusion is made that central locomotor generator activity modulates the level of primary afferent depolarization.
