摘　　要：以柞蚕 5龄幼虫为材料 ,运用微电极电生理技术 ,以细胞外记录方法记录了柞蚕幼虫在体脑神经节的自发放电活动 ,并观察了胞外Na+、K+、Ca2 +的浓度变化对放电活动的影响。结果表明 ,柞蚕幼虫脑神经节的胞外放电活动有 3种形式 ,其离子机制可能既有Na+动作电位 ,又有Ca2 +动作电位。In this paper,the Antherae pernyi larvae were selected as experimental materials,microelectrode technique was used to record spontaneous electrical activity of cerebral ganglions,the effect on electrical activity with various Na +,K + and Ca 2+ concentration was observed too.The results indicated that there were three forms of spontaneous electrical activity of Antherae pernyi larvae.The ionic mechanisms perhaps include both Na + and Ca 2+ action potential.
