用菜豆-白细胞凝集素（PHAL）法观察了成年雄性大鼠终纹床核前区中脑囊核（BSTju）的轴突投射。我们的研究结果表明，BSTju显示一个相对简单的投影模式。首先，它密集地支配内侧中央杏仁核和连合下区和参与内脏反应的BST细胞群的尾侧前外侧区。第二，它提供输入到腹内侧尾壳核（CP）和前基底外侧杏仁核-可能调节躯体运动流出的区域。第三，BSTju发送密集的投影到尾侧无名质，黑质致密部分的一个独特的尾侧背外侧区域，以及相邻的中脑网状核和红核后区。第四，BSTju向边缘前、边缘下和腹侧CA 1皮质区提供光输入;向后基底外侧、后基底内侧和外侧杏仁核提供光输入;向丘脑室旁核和内侧背内侧核提供光输入;向下丘脑的丘脑底核和丘脑底旁核提供光输入;向中脑导水管周围灰质腹外侧提供光输入。这些预测，在一定程度上，表明BSTju在电路整合自主反应与躯体运动活动的自适应行为的作用。(C)2000 Elsevier Science B.

The axonal projections of the juxtacapsular nucleus of the anterior division of the bed nuclei of the stria terminalis (BSTju) were examined with the Phaseolus vulgaris-leucoagglutinin (PHAL) method in the adult male rat. Our results indicate that the BSTju displays a relatively simple projection pattern. First, it densely innervates the medial central amygdalar nucleus and the subcommissural zone and caudal anterolateral area of the BST - cell groups involved in visceromotor responses. Second, it provides inputs to the ventromedial caudoputamen (CP) and anterior basolateral amygdalar nucleus - areas presumably modulating somatomotor outflow. Third, the BSTju sends dense projections to the caudal substantia innominata, a distinct caudal dorsolateral region of the compact part of the substantia nigra, and the adjacent mesencephalic reticular nucleus and retrorubral area. And fourth, the BSTju provides light inputs to the prelimbic, infralimbic, and ventral CA1 cortical areas; to the posterior basolateral, posterior basomedial, and lateral amygdalar nuclei; to the paraventricular and medial mediodorsal thalamic nuclei; to the subthalamic and parasubthalamic nuclei of the hypothalamus; and to the ventrolateral periaqueductal gray. These projections, in part, suggest a role for the BSTju in circuitry integrating autonomic responses with somatomotor activity in adaptive behaviors. (C) 2000 Elsevier Science B.V.
