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

这种长期性变化可能是由于中枢经系经可塑性变化起（从脊髓背层）。

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.

说明背浅层内GABABR-LI终末分别来自外周初级传入、脊髓以上脑结构和背浅层内中间经元。
