应用立体定位、核团内注射与电解损毁核团技术及微电极细胞外记录方法，以猫丘脑后核内脏大神经诱发单位放电为内脏痛指标，观察向尾状核、中脑导水管周围灰质及杏仁内侧核内注入东亚钳蝎毒及在电解损毁３个核团前后ＰＯ内脏大神经诱发单位放电的变化。在损毁诸核之前刺激内脏大神经引起单位诱发放电，损毁诸核之后诱发放电减弱或消失，这与辽宁产东亚钳蝎毒注入诸核团中的作用相一致。表明蝎毒的作用部位与上述核团有关，更进一步证明蝎毒作用部位 Using stereotactic, intranuclear injection and electrolytic damage nuclei technology and microelectrode extracellular recording method, the unit discharge of visceral large nerve in cat’s thalamic nucleus was taken as visceral pain index, and the changes to the caudate nucleus, periaqueductal gray matter And into the medial almonds injected with Asiatic toxoplasma vascularis and changes of PO visceral nociceptive discharges before and after the three nuclei were damaged by electrolysis. In order to damage the nucleus before stimulating the visceral nerve caused by unit-induced discharge, damage to the nucleus after the induced discharge weakened or disappeared, which Liaoning and East Asia clamp scorpion venom injected into the nucleus in line with the role. That part of the role of scorpion venom and the above-mentioned nuclear, and further prove that the role of scorpion venom site
