Abstract:
The antidromic C waves elicited by stimulating the entry zone of the dorsal root were recorded in spinal toads. Influences if conditioning stimuli in 60 T from sciatic nerve on antidromic C waves were observed. The conditioning stimuli produced marked increace in the excitability of the C-afferent terminals. The increased excitability possessed two phases. The results indicat that periphiral primary afferent A and C-fibres can produce presynaptic inhibition in C-fibre terminals.
