形态学资料和电生理实验证明,缰核是前脑边缘结构至脑干的中间枢纽,它接受隔区、视前区、海马、伏隔核等的抑制性作用,进而对脑干的有关核团如中缝核、蓝斑核的活动进行调节,从而加强针刺镇痛效应。本实验以整体动物的甩尾阈值为指标,确定并衡量缰核对基础痛阈的影响和在针刺镇痛中的作用。 Morphological data and electrophysiological experiments show that the habenula is the central junction of the marginal structure of the forebrain and the brainstem. It accepts the inhibitory effects of the septal area, the preoptic area, the hippocampus, the nucleus accumbens, and so on, Mission such as the stitched nucleus, locus coeruleus activity regulation, thereby enhancing acupuncture analgesic effect. In this experiment, the tail flick threshold of whole animals was used as an index to determine and measure the influence of habenular nucleus on the basis of pain threshold and the role in acupuncture analgesia.
