Figure 6

Rate histograms show the effect of CGRP (10 μg) post-treatment on the responses of single Aδ- (A) and C-fibers (B) to mechanical stimuli after CAP injection under dorsal rhizotomized conditions. Top row: Responses to mechanical stimuli before CAP injection. Second row: 45 min in Aδ-fiber and 30 min in C-fiber after CAP injection, an obviously enhanced response to mechanical stimuli was seen after intra-arterial CGRP treatment 10 min after CAP injection under dorsal rhizotomized conditions. Bottom row: 60 min after CAP injection, the enhanced response to mechanical stimuli decreased. Bin width: 1 s.
