[Phase-modulated antidromic action potentials in the dorsal root of the rat during locomotion]

Discharges of antidromic spike potentials (ASP) were recorded from the rat dorsal root during locomotion. Tonic and phasic components were revealed in discharges of ASP. The phase-dependent modulation of phasic component was observed during locomotion. The role of ASP as a possible mechanism for restriction of afferent input was discussed.
