查询词典 inhibitory nerve

BACKGROUND: F-wave is a late muscle response which results from the antidromic activation of spinal motorneurones following peripheral nerve supramaximal electrical stimulation,and influenced by the balance of excitatory and inhibitory postsynaptic potentials on spinal motomeurons.

The inhibitory efFect of deep somatic nerve stimulation on the HVEs does not depend upon the buffer nerves, but is related to the function of medial medulla oblongata.

上述结果表明：化学感受性反射能易化刺激下丘脑诱发的室性期前收缩，而压力感受性反射可以抑制这种室性期前收缩，但躯体传入冲动对这种心律失常的抑制作用并不依赖于缓冲神经的存在，而有赖于延做中线核群的完整性。

Furthermore, in the CTA rats, compared with water stimulability, FLI neurons of SON and DMV induced by sucrose stimulability had had much more expressions.6 When the same sucrose stimulability was given, FLI neurons expressions of SON, DMV and LH in the CTA rats were much lowwer than that in the control rats.Conclusions:1 CTA had an inhibitory effect on small intestine peristalsis, indicate taste preference has an effect on small intestine peristalsis, and inhibitory effect induced by CTA is corresponded with US, this effect may have relations with vagus efferent never and humoral regulation.2 In the electrophysiology experiment, discharges of vagus efferent never in the CTA rats are much more than that in the control rats, indicates taste and taste preference may regulate small intestine peristalsis via vagus nerve, and dicharge can continude 1 hour, indicate humoral regulation also exists in the regulation.

结论1建立味觉厌恶对小肠运动有抑制作用，提示味觉嗜好性对小肠运动有影响，而且味觉厌恶引起抑制作用是与条件刺激成对应关系的，味觉刺激引起的小肠蠕动的抑制作用可能与迷走神经传出神经及体液调节有关。2在电生理实验中，CTA大鼠迷走神经传出放电高于对照组的大鼠，提示味觉及味觉嗜好性可能是通过迷走神经对小肠运动进行调节的，放电至能持续60min，表明味觉及味觉对小肠运动的调节中还有体液调节的参与。

And the Akt of activation carries gene of phosphation Bad, GSK-3, transcribe familial, IB, Caspases make close to wither dies gene misses work, have inhibitory nerve thereby yuan wither dies reach stimulative nerve yuan surviving action, reduce AD nerve then yuan many and missing, the pathology that improves AD changes.
