应用逆向激活碰撞技术并结合神经元电生理学特征分析,发现中缝背核有纤维直接投射到丘脑束旁核,且这些中缝-丘脑单位中约40%是5-羟色胺能神经元;束旁核对中缝背核活动也存在影响。讨论了两核团间联系性质及其在痛信号传递及调制中的意义。
Using reverse-activated collision technology combined with electrophysiological characteristics of neurons, it was found that the dorsal raphe nuclei project directly to the paraventricular nucleus of the thalamus, and about 40% of these medial - thalamic units are serotonergic neurons; Dorsal nuclear activity also has an impact. Discussed the nature of the association between the two nuclei and their implications for pain signal transmission and modulation.
