Responses of 71 single salivatory neurons, identified by antidromic spikes evoked by stimulation of the chorda tympani, were tested to stimulation of the ipsilateral infraorbital (IO), inferior alveolar (IA) and lingual nerves (LN) in the cat. Fifty-one neurons responded with spike potentials to stimulation of one or more of these nerves (responsive type, R), while the remaining 20 neurons did not respond to stimulation of any of them (non-responsive type, NR). Thirty-three R neurons were activated by stimulation of all of the 3 trigeminal afferent branches, while 12 neurons responded with spikes to stimulation of only one branch, usually of LN. Reflex spike responses appeared with a latency of 5.6-14.6 ms to LN stimulation, 6.4-15.7 ms to IO stimulation and 6.0-26.0 ms to IA stimulation. Impulses of both A beta and A delta afferent fibres of the trigeminal nerve were found to be effective for activation of salivatory neurons.
通过刺激鼓索神经诱发的逆向动作电位识别出71个单唾液腺神经元，测试了猫的同侧眶下神经（IO）、下牙槽神经（IA）和舌神经（LN）对这些神经元的刺激反应。51个神经元对这些神经中的一种或多种刺激产生动作电位反应（反应型，R），而其余20个神经元对任何一种刺激均无反应（无反应型，NR）。33个R神经元被所有3个三叉神经传入分支的刺激所激活，而12个神经元仅对一个分支（通常是LN）的刺激产生动作电位反应。对LN刺激的反射性动作电位反应潜伏期为5.6 - 14.6毫秒，对IO刺激为6.4 - 15.7毫秒，对IA刺激为6.0 - 26.0毫秒。发现三叉神经的Aβ和Aδ传入纤维的冲动对唾液腺神经元的激活均有效。
