实验用神经元逆行荧光标记和儿茶酚胺荧光组化联合法研究大白鼠交叉性黑质一纹状体通路。一侧尾壳核注射标记物后,对侧黑质和其邻近部位均能见到少最逆行标记细胞。这种细胞在一侧脑内约有80个。上述对侧性标记细胞主要见于黑质后部脚间核平面,分散在黑质致密部内侧份、被盖腹侧区外侧份和附近部位。双侧尾壳核注射不同标记物后,没有看到双标记细胞,提示交叉性和同侧性黑质一纹状体投射通路分别由不同细胞的轴突所组成,灌注能诱发儿茶酚胺神经元产生荧光的Eaglu后,表明这些对侧性标记细胞绝大部分为多巴胺能神经元。
Experimental neuronal retrograde fluorescent labeling and catecholamine fluorescence combined with the study of rat cross nigrostriatal pathway. One side of the caudate putamen injection of markers, the contralateral nigral and its adjacent parts can see less retrograde labeled cells. There are about 80 such cells in one side of the brain. The contralateral marker cells mainly seen in the substantia nigra posterior interventricular nucleus plane, scattered in the substantia nigra pars compacta inner part, is covered ventral area of the outer side and nearby parts. Bilateral caudate putamen after injection of different markers, did not see the double-labeled cells, suggesting that the intersection and ipsilateral nigrostriatal injection pathways are composed of different cell axons, perfusion can induce catecholamine neurons Fluorescent Eaglu, indicating that most of these contralateral marker cells for dopaminergic neurons.
