投射至前庭神经下核的猫小脑浦氏细胞的分布—HRP逆行追踪研究

The Distribution of Purkinje Cells Projecting to the Descending Vestibular Nucleus of the Cat--by Retrograde Labelled of HRP

将ＨＲＰ定位注入至前庭神经下核（ＤｅｓｅｎｄｉｎｇＶｅｓｔｉｂｕｌａｒＮｕｃｌｅｕｓ，ＤＶＮ），观察逆行标记的浦氏细胞在小脑皮质的分布。ＨＲＰ注入ＤＶＮ时，标记细胞（Ｌａｂｅｌｅｄｃｅｌｓ，ＬＣ）出现在Ⅰ～Ⅹ小叶的同侧，主要分布在小叶的基底部和中间部，小叶尖端很少，其中Ⅸ和Ⅹ小叶最多（４９．４％和１６．７％）；分布在Ⅰ～Ⅴ小叶的ＬＣ呈纵长带状分布，此带宽约１．０ｍｍ，Ⅰ～Ⅱ小叶位于Ｖｏｏｇｄ［１］的Ａ２、Ｂ１带，其余位于Ｂ１、Ｂ２带内，分布在Ⅸ小叶的ＬＣ分为距正中线０．５ｍｍ以内的内侧带和１．０～１．７ｍｍ的外侧带。Ⅹ小叶的ＬＣ从中线向外呈均匀分布。

After injections of HRP into the descending vestibular nucleus (DVN), we observed the distribution of retrograde labelled purkinje cells (LC) in the cerebellar cortex of the cat. following injections of HRP into the DVN, LC were seen in lobules Ⅰ～Ⅹ of the ipsilateral to the DVN of injections of HRP. They were mainly located in basal and middle part of the lobules, in apical part were very a few. They were most numerous in lobules Ⅸ and Ⅹ(47.1% and 19.1%). LC in lobules Ⅰ～Ⅴ were distributed as a longitudinal band, the width of this hand is adout 1.0mm. In lobules Ⅰ～Ⅱ this band was located at A 2 and B 1 Zones, the other part of this band was located at B 2 and C 1 zons of Voogd. LC in lobule Ⅸ may identified within 0.5mm of the midline as a medial band and between 1.0～1.7mm of the midline as a lateral band.
