  • Title: Rhythmic antidromic discharges of single primary afferents recorded in cut dorsal root filaments during locomotion in the cat.
    Author: Dubuc R, Cabelguen JM, Rossignol S.
    Journal: Brain Res; 1985 Dec 16; 359(1-2):375-8. PubMed ID: 4075157.
    Abstract:
    Single units recorded in the proximal stump of cut dorsal root filaments were found to antidromically discharge rhythmically during fictive locomotion in decorticate and paralyzed cats. Some units fired throughout the period of flexor or extensor nerve activity, whereas other units discharged near the transitional phases. Similar findings were made in acutely spinalized and paralyzed cats injected with L-DOPA, as well as in non-paralyzed decorticate cats walking on a treadmill. These results suggest that different types of primary afferents may be depolarized cyclically at different specific time in the step cycle by the central pattern generator for locomotion, and that this central control of the primary afferents may be involved in the modulation of the reflex transmission observed during locomotion.
