Abstract
γ-aminobutyric acid (GABA)-containing neurons are densely located in laminae Ⅰ—Ⅱ of the spinal cord where substance P (SP)-containing primary afferent C fibers terminate. By the antibody microprobe technique, we found that capsaicin, a chemical irritant selectively activating C fibers, significantly produced the release of SP in lamina Ⅱ. The
