【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。更多还原

【Abstract】 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.更多还原
