鸡端脑和下丘脑向面神经腹侧核的传出性纤维联系──HRP逆行追踪法

The Afferent Connections of he Ventral Facial MotorNucleus from Telencephal and Hypothalamus in Chicken,Retrograde Tracing by HRP

将２０％ＨＲｐ水溶液注射于鸡的面神经腹侧核，逆行追踪支配该部的有关高位神经核团。结果于端脑、下丘脑和脑干内出现标记细胞，瑞脑内的标记细胞较多地出现于古纹状体，少量出现于旧纹状体腹侧与枕中脑束之间的区域，两群标记细胞形态上明显不同。下丘脑的标记细胞较多地出现于下丘脑后区，室旁核出现少量，个别散在于下丘脑其他区域。

HRP (horseradish peroxidase)solution was injected into the ven-tral facial motor mucleus of chicken in order to retrograde trace telencephalic and hv-pothalamic neurons which innervate the injected nucleus.The results were as follows:1.More labelled cells located in the dorsalateral part of the jpsilateral achistriatum,2.Asmall number of labelled cells lied within the area between ipsilateral tractus occipito-mesencephalous and ipsilateral paleostriatum.3. Some labelled cells lied bilaterallywithin the area hypothalami posterioris (AHP) and ipsilaterally within the nucleus par-aventricularis in hypothalamus.
