猫延髓吻侧腹外侧区与孤束核的纤维联系——WGA-HRP法研究

THE FIBER CONNECTIONS BETWEEN THE ROSTRAL VENTROLATERAL MEDULLA AND THE NUCLEUS TRACTUS SOLITARII IN THE CAT : A WGA-HRP STUDY

将WGA-HRP经背路或腹路注入成年家猫一侧延髓吻侧腹外区(RVL),在双侧孤束核(NTS)观察到逆行标记的细胞.标记细胞主要位于NTS尾侧份的内侧亚核、外侧亚核和腹外侧亚核。并见RVL注射区有顺行标记纤维投射至双侧NTS及对侧RVL。标记纤维在NTS吻侧半最为明显。

After injection of WGA-HRP into the rostral ventrolateral medulla(RVL) of adult cats through a dorsal or ventral path, the retrograde labelled cells were found bilaterally in the nucleus tractus solitari(NTS).Most of the labelled cells were situated in the medial, lateral 'and ventrolateral subnuclei of the caudal part of the NTS. The anterograde labelled fibers projecting into the bilateral NTS and the contralateral RVL from the injection site were also found. The labelled fibers in the rostral part of the NTS were most abundant.
