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

这种长期性的变化能是由于中枢神系统的神性变化起的（从角到皮层）。

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.

说明角浅层内的GABABR-LI终末分别来自外周初级传入、以上的脑结构和角浅层内的中间神元。
