One GABA-IR positive nerve fiber could form synapse with 6-7 OHCs.
一根GABA - IR阳性的神经纤维，在外毛细胞区可形成6 ~ 7个终末。
Under TEM, GABA-IR positive efferent endings, negative efferent endings and negative afferent endings could be seen on the OHC bases.
免疫电镜发现在外毛细胞底部有GABA - IR阳性的传出神经末梢及阴性的传入、传出神经末梢。
Results: GABA-IR structure of both groups was observed in amacrine cells, inner plexiform layer, ganglion cells and nerve filament layer.
结果：老年猫、青年猫GABA免疫反应阳性结构均见于无长突细胞、内网状层、神经节细胞和神经纤维层。
