Abstract

The field potentials evoked by electrical stimulation of the afferent A delta fibers of the ipsilateral carotid sinus nerve (CSN) were surveyed in all the regions of the nucleus tractus solitarii of the cat (NTS responses). Pressor and inspiratory responses, like the CSN chemoreceptor reflex, are elicited by electrical stimulation of the site of the NTS responses in the rostral regions, the lateral portions of the intermediate regions and the commissure regions. On the other hand, depressor and apneic responses, like the CSN baroreceptor reflex, are elicited by electrical stimulation of the site of the NTS responses in the medial portions of the intermediate regions and the dorsal portions of the commissure regions.

摘要

在猫孤束核的所有区域测量了由电刺激同侧颈动脉窦神经(CSN)的传入Aδ纤维所诱发的场电位(NTS反应)。在延髓头端区域、中间区域外侧部分和连合区域中,对NTS反应部位进行电刺激,可引发升压反应和吸气反应,如同CSN化学感受器反射。另一方面,在中间区域内侧部分和连合区域背侧部分中,对NTS反应部位进行电刺激,可引发降压反应和呼吸暂停反应,如同CSN压力感受器反射。
