Abstract

Afferent connections to the medial hypothalamic region in the rat were studied using horseradish peroxidase (HRP). HRP was injected iontophoretically by a parapharyngeal approach. After HRP injections into the ventromedial hypothalamic nucleus, labeled cells were found mainly in the medial and basolateral amygdaloid nuclei, subiculum, peripeduncular nucleus and the parabrachial area. Labeled cells following HRP injections into the dorsomedial hypothalamic nucleus were found mainly in the lateral septal nucleus, nucleus accumbens, bed nucleus of the stria terminalis, pontine central gray and the parabrachial area. HRP-labeled cells following the medial preoptic area injections were found mainly in the infralimbic cortex, lateral and medial septal nuclei, nucleus accumbens, diagonal band, bed nucleus of the stria terminalis, medial amygdaloid nucleus, subiculum, peripeduncular nucleus and the parabrachial area. The intrahypothalamic connections were also discussed.

摘要

采用辣根过氧化物酶(HRP)对大鼠下丘脑内侧区域的传入联系进行了研究。通过咽旁途径以离子电渗法注射HRP。将HRP注入腹内侧下丘脑核后,标记细胞主要见于杏仁内侧核和基底外侧核、海马下脚、脚周核和臂旁区。将HRP注入背内侧下丘脑核后,标记细胞主要见于外侧隔核、伏隔核、终纹床核、脑桥中央灰质和臂旁区。将HRP注入视前内侧区后,标记细胞主要见于边缘下皮质、外侧和内侧隔核、伏隔核、斜角带、终纹床核、杏仁内侧核、海马下脚、脚周核和臂旁区。还讨论了下丘脑内的联系。
