Abstract: | The development of intensive depolarization of terminals through stimulation of the afferent nerve or dorsal root of sufficient strength causes the appearance of antidromic discharges recordable as a dorsal-root reflex. The discharges were shown to spread simultaneously in the dorso-ventral direction, with consequent facilitation of spinal reflexes. The results suggest the possible existence of two types of effect of presynaptic depolarization on spinal afferent pathways. |
