Plastic changes in nociceptive transmission may occur at the spinal cord as well as supraspinal structures after tail amputation.

这种的变化可能是由于中枢神经系统的神经可塑变化起的（从脊髓背角到皮层）。

These results indicate that GABABR-LI terminals in the spinal dorsal horn originate from peripheral afferent fibers, supraspinal structures and interneurons within the spinal dorsal horn.

说明背角浅层内的GABABR-LI终末分别周初级传入、脊髓以上的脑结构和背角浅层内的中间神经元。
