本文在猫耳蜗前腹侧核(AVCN)内制作了毁损灶,用Nauta法和Protargol法研究了AVCN投射的变性。溃变纤维投射至病变侧外侧上级橄榄核和斜方体外侧核,两侧内侧上级橄榄核、外侧丘系腹侧核、背侧核和下丘中央核。斜方体的退变似乎有两个纤维成分:背侧部分进入对侧内侧上级橄榄核,腹侧部分不。AVCN向同侧斜方体外侧核后部、同侧斜方体腹侧核后部或对侧斜方体内侧核后部的投射很少。耳蜗投射到AVCN的有序排列似乎在AVCN投射到上级橄榄核中得到保留。结果表明,两个投影的路线和连接不同,但起源于AVCN的一个分区。
Lesions were made in the anterior ventral cochlear nucleus (AVCN) of the cat. Degeneration in the projections of the nucleus was studied with the Nauta and protargol methods. Degenerated fibers were found projecting to the lateral superior olivary nucleus and the lateral nucleus of the trapezoid body on the side of the lesion, and to the medial superior olivary nucleus, ventral and dorsal nuclei of the lateral lemniscus, and central nucleus of the inferior colliculus on both sides. Degeneration in the trapezoid body appears to have two fiber components: a dorsal portion that enters the contralateral medial superior olivary nucleus, and a ventral portion that does not. The AVCN has few, if any, projections to the posterior parts of the ipsilateral lateral nucleus of the trapezoid body, ipsilateral ventral nucleus of the trapezoid body, or to the contralateral medial nucleus of the trapezoid body. The orderly arrangement of the cochlear projection to the AVCN appears to be preserved in the projection of the AVCN to the superior olivary nuclei. The results suggest that two projections, differing in their course and connections, originate in a single subdivision of the AVCN.
