以~3H—亮氨酸为示踪剂,应用放射自显影技术顺行追踪S.D种系大白鼠下丘脑室旁核的传出纤维联系。室旁核内侧份到杏仁核群和海马结构有丰富的纤维投射。在杏仁前区背侧部、杏仁内侧核、杏仁中央核、终纹床核杏仁内部、杏仁基底核、杏仁中介核、杏仁海马移行区、海马下托腹侧部,CA_1和CA_2内都发现密集的标记纤维终末。这些投射为双侧性,但同侧占优势。室旁核内侧份发出的纤维经终纹、杏仁腹侧径路和视上连合投射到杏仁核群。一部分纤维穿过杏仁核群继续向尾侧经杏仁海马移行区投射到海马下托腹侧部、CA_1、和CA_2等广泛区域。
Using 3H-leucine as a tracer, autopoietic techniques were used to trace the outgoing fibers in the hypothalamic paraventricular nucleus of S.D gerbils. Ventricular paraventricular nucleus to the amygdala and hippocampal structures rich in fiber projection. In the dorsal part of anterior almond, the medial almond, the almond central nucleus, the inside of the terminal bed nucleus almond, the almond basement nucleus, the almond nucleus, the almond hippocampal transitional area, the hippocampus inferior ventral part, CA_1 and CA_2 are found dense The marker fiber end. These projections are bilateral, but ipsilateral predominates. Intraventricular paraventricular nucleus issued by the fiber end of the line, almond ventral path and the commissure projected onto the amygdala. Part of the fiber through the amygdala group continue to the caudal side of the almond hippocampal transitional area projected to the hippocampus under the ventral abdominal area, CA_1, and CA_2 and other areas.
