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终末分别来自外周初级传入、脊髓以上的脑结构和背角浅层内的中间神经元。

After partial deafferentation of spinal cord of adult cat, the expression of NGF in dorsal horn, which is the target area of dorsal root afferent fibers, up-regulated.

成年猫脊髓部分背根传入纤维损伤后，其背角靶区内NGF的表达又明显增加，可能是诱导未受损伤的背根——备用背根纤维在脊髓内侧枝出芽的一个重要因素。
