臂旁核
Nuclei parabrachiales
定义
In the human brain, parabrachial nucleus (臂旁核) is a horseshoe-shaped strip of gray matter comprising the subparabrachial nucleus (臂旁下核), the lateral parabrachial nucleus (外侧臂旁核) and the medial parabrachial nucleus (内侧臂旁核). It is located at the junction of the midbrain and 脑桥 in the lateral reticular formation, rostral to the parvocellular reticular nucleus near the superior cerebellar peduncle. It gets its name from its closeness to the superior cerebellar peduncle.
在人脑中，臂旁核是一条马蹄形的灰质带，由臂旁下核、外侧臂旁核和内侧臂旁核组成。它位于中脑与脑桥交界处的外侧网状结构内，在小脑上脚附近，位于小细胞网状核的吻侧。其名称源于其与小脑上脚的毗邻关系。
臂旁核接收来自孤束核尾侧部的信号，并向延髓下部、脊髓、杏仁核及下丘脑外侧区发送信号；内侧臂旁核将来自孤束核头侧味觉部分的信息中继至丘脑腹后内侧核；外侧臂旁核接收来自尾侧孤束的信息，并主要将信号传递至下丘脑内侧区，同时也传递至下丘脑外侧区以及内侧臂旁核所投射的许多其他神经核。
