摘要: 目的:验证中缝背核与缰核间的电活动及其功能联系。方法:分别在中缝背核和缰核埋置套管,采用微量注射、电刺激及细胞外记录的方法,观察缰核及中缝背核细胞单位放电。结果:阻断中缝背核,外侧缰核神经元放电频率增加(58%),内侧缰核神经元放电频率减少(56%);电刺激中缝背核,外侧缰核神经元放电频率减少(61%),内侧缰核神经元放电频率增加(52%)。阻断缰核,中缝背核神经元放电频率以兴奋为主(53%单位自发性放电频率增加);电刺激缰核,中缝背核神经元放电频率以抑制为主(62%单位自发性放电频率减少)。结论:缰核与中缝核之间存在密切的功能联系。

Abstract: Objective To identify the lectrophysiological relationship between dorsal raphe(DR) and habenular nucleus(Hb). Methods Using the methods of microinjection and electrical stim ulation and extracellular discharge recording to observe the discharge of Hb and DR. Results Of responsive neurons in Hb to DR blocked, 58% in the LHb was activated and 56% in the MHb was suppressed. Of responsive neurons to DR stimulated, 52% in the MHb was activated and 61% in the LHb was suppressed. The neurons of DR were significantly excited (53%) when Hb was blocked. The neurons of DR were depressed (62%) when Hb was stimulated. Conclusion The experimental results demonstrate that there are close functional links between DR and Hb.
