Abstract
Electric stimulation of the peripheral stump of cervical sympathetic nerve (0.5-5.0 sec trains at 1 msec, 6-10 V, 0.5-30 HZ) induced in jaw muscle spindle afferents: (1) decrease of discharge frequency with 0.6-2.5 sec latency, lasting 8-13 sec (in 40% of the units) possibly due to direct sympathetic innervation of spindles; and (2) subsequent modest increase of frequency, probably secondary to muscular vasoconstriction.
摘要
对颈交感神经外周残端进行电刺激（以1毫秒、6 - 10伏、0.5 - 30赫兹进行0.5 - 5.0秒的串刺激），在颌部肌梭传入神经中引发了：（1）放电频率降低，潜伏期为0.6 - 2.5秒，持续8 - 13秒（在40%的单位中出现），这可能是由于肌梭的直接交感神经支配；以及（2）随后频率适度增加，可能继发于肌肉血管收缩。
