摘　　要：本文采用微电极引导神经元放电的方法证明,长时间(6小时)电针(EA)大鼠“足三里”穴可使痛兴奋神经元(PEN)和痛抑制神经元(PIN)的放电产生耐受现象,即EA不再对PEN和PIN的放电产生调制作用。从细胞水平上得到的这一证据支持行为水平上的结果。According to the method of neuronal discharges let out by microelectrodes in this report, it is demonstrated that electric discharges of pain excited neurons (PEN) and pain inhibited neurons (PIN)in nucleus parafascicularis of rat thalamus can not obviously change through long-term electroacupuncture (EA) 'Tsusanli' points, i. e. it is tolerant to EA analgesia. This evidence from the cell level supports the investigation on behavioral level of the rat.
