摘要
本实验用HRP法探讨了大白鼠耳蜗核、前庭神经间质核及小脑核至小脑半球与后蚓部的投射。结果证明耳蜗核与前庭神经间质核仅有少量神经元直接投射至小脑后蚓部皮层。小脑核中的顶核有较多的神经元投射至后蚓部,而间位核与齿状核则仅有少量神经元投射至该区。另外,发现顶核至小脑半球的投射系交叉性的,即右侧顶核投射至左侧小脑半球。
1.The connections between the cochlear nucleus,interstitial nucleus of the vestibular nerve,cerebellar nuclei and the cerebellar cortex of the vermis and hemisphere were studied by means of the HRP method.2.The labelled cells were found in the cochlear nuclei bilaterally as well as in the interstitial nucleus of the vestibular nerve and cerebellar nuclei,but the labelled cells did not appear in the superior olivary complex or inferior colliculus when the injection of HRP was given to the cerebellar cortex of vermis.3.There are three types of the lebelled cells in the cochlear nucleus and the number of these cells in one cochlear nucleus did not exceed 20.4.The labelled cells in the interstitial nucleus of the vestibular nerve and cerebellar nuclei were found bilaterally when the injection was given to vermisⅧⅧ.But the labelled cells were only found in the fastigial nucleus contralaterally when the injection was given to the cerebellar hemisphere of oneside.
