Extracellular microelectrode method and stereotaxic technique of brain were used to investigate the effects of Radix Salviae Miltiorrhizae on the discharges of visceral pain in the posterior nucleus of thalamus(po)in cats. Experiments showed that Radix Salvia Miltiorrhizae inhibited the discharges of visceral pain in po, Radix Salviae Miltiorrhizae acts directly on the peripheral nerve trunk and cannot block its exciting conduction. This suggests that the analgesic effect of Radix Salviae Miltiorrhizae is exerted via central nervous system.
采用细胞外微电极方法和脑立体定位技术，观察丹参对猫丘脑后核内脏痛放电的影响。实验表明，丹参可抑制猫丘脑后核内脏痛放电，丹参对周围神经干无直接作用，不能阻断其兴奋传导。提示丹参的镇痛作用是通过中枢神经系统实现的。
