Abstract:
No significant difference in peak amplitude, duration, latency and wave integral between A-DRP and CDP-P_1 was electrophysiologically observed in control and capsaicin-treated adult rats which had been injected at birth with capsaicin(50mg/kg,s.c.), when the sural nerves were stimulated. However, the most of C-DRP and CDP-P_2 lack. These were consistent with the changs of peripheral action potentials. The above results suggest that PAD on myelinated primary afferent fibres produced by incoming volleys in the larger afferent is not affected by a lifelong loss of Group Ⅳ afferent, but the afferent responses of amall fibres disapear.
