摘　　要：目的 :观察大白鼠海马至下丘脑和外侧隔核的分枝投射。方法 :采用荧光素双标记 ,将樱草黄 (Pr)、双苯甲亚胺 (Bb)分别注射到大白鼠右侧下丘脑和左侧外侧隔核 ,观察海马中的逆行标记细胞。结果 :双侧海马内均见到Pr单标记细胞、Bb单标记细胞以及Pr/Bb双标记细胞。结论 :大白鼠海马至下丘脑和外侧隔核有纤维联系和分枝投射。Objective To observe the divergent axon collaterals from hippocampus to hypothalamus and lateral septal nuclei in the rat.Method By means of fluorescein double label,primuline(Pr) and bisbenzimide(Bb) were injected into rat right hypothalamus and left lateral septal nuclei respectively,observing the retrograde labeled cells in hippocampus.Result Pr single labeled cells,Bb single labeled cells and Pr/Bb double labeled cells were found in bilateral hippocampi.Conclusion The refrograde double labeled cells in the hippocampi may divergently projected to the hypothalamus and lateral septal nuclei.
