目的：研究伤害性刺激对大鼠杏仁核簇中各亚核痛反应神经元电活动的影响。
Aim: To research the influence of noxious stimuli on the electric activities of pain related neurons in several subnuclei of Amygdaloid Nucleus in rats.
电刺激对侧的HCN也能抑制PO核中多数内脏痛反应神经元的活动，其抑制作用与同侧比较无明显差异。
The inhibition of HCN stimulation was bilateral and no statistical differences were found between the effects of contralateral and ipsilateral HCN stimulation on the neurons in PO.
结论：CCK - 8的抗ea镇痛作用在中枢痛反应神经元电活动和整体行为反射水平上是协调一致的。
Conclusion: the antagonism of CCK-8 to analgesic effect of EA shows the coordinative and consistent actions on the levels of discharges of central pain-related neurons and the whole behavior reflex.
结论：褪黑色素可通过作用于外侧缰核的阿片受体而影响其痛相关神经元对痛刺激的反应，这可能是褪黑色素中枢镇痛机制之一。
Conclusion: Melatonin can change the responses of pain neurons to pain stimulation via opioid receptor in the LHb, which might be one of analgesic mechanisms by MEL.
