Neuronal activity was recorded in nucleus paragigantocellularis lateralis (PGL) of the cat in response to stimulation of the dorsal periaqueductal grey matter (dPAG), parabrachial nucleus (PBN) nucleus raphe magnus (NRM), and nucleus tractus solitarii (NTS). Stimulation in dPAG or PBN evoked excitatory responses whilst the prevalent response to stimulation in NRM or NTS was inhibition of neuronal activity. 45/55 (82%) of cells tested received convergent inputs from 2 or more sites of stimulation. These findings are discussed in relation to the role of PGL in cardiovascular control and descending control of noxious input.
在猫的外侧旁巨细胞旁核（PGL）中记录神经元活动，以响应背侧导水管周围灰质（dPAG）、臂旁核（PBN）、中缝大核（NRM）和孤束核（NTS）的刺激。dPAG或PBN的刺激诱发兴奋性反应，而对NRM或NTS刺激的普遍反应是神经元活动的抑制。45/55（82%）的受试细胞接受来自2个或更多刺激部位的汇聚输入。结合PGL在心血管控制和有害输入下行控制中的作用对这些发现进行了讨论。
