Stimulation of the nasal mucosa produces a number of respiratory reflexes the afferent limb of which is provided by the ethmoidal nerve, a branch of the trigeminal nerve. In the cat this nerve terminates within the trigeminal nucleus. It has no direct projection to brainstem respiratory centres. This study examines the response of respiratory-related neurones in the nucleus of the solitary tract (NTS) to ethmoidal stimulation. It demonstrates that these neurones show both excitatory and inhibitory responses to ethmoidal stimulation. Thus, the NTS appears to be involved in respiratory reflexes initiated by stimulation of the nasal mucosa.
刺激鼻黏膜会产生多种呼吸反射，其传入支由三叉神经的分支筛神经提供。在猫中，该神经在三叉神经核内终止。它没有直接投射到脑干呼吸中枢。本研究考察了孤束核（NTS）中与呼吸相关的神经元对筛神经刺激的反应。结果表明，这些神经元对筛神经刺激表现出兴奋和抑制反应。因此，孤束核似乎参与了由鼻黏膜刺激引发的呼吸反射。
