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

这种长期性的变化可能是由于中枢神的神可塑性变化起的（从脊髓背角到）。

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.

明背角浅内的GABABR-LI终末分别来自外周初级传入、脊髓以上的脑结构和背角浅内的中间神元。
