一、引言近年来,电生理的研究中采用了尖端仅约0.5微米的玻璃管状微电极,可以在极少损伤的情况下,记录出单个细胞的电变化,因此能在细胞水平上研究生物电的发生、传导和传递的机制,以及在许多生理现象中单个神经细胞的电活动,使工作大大深入,这对于难以进行离体实验的中枢神经系统更加重要.于是,微电极技术就成了电生理研究中的有力工具.随着微电极
I. INTRODUCTION In recent years, the electrophysiological study used a glass tubular microelectrode with a tip of only about 0.5 micrometer to record the electrical change of a single cell with minimal damage, thus allowing the study of bioelectricity at the cellular level The mechanism of conduction, conduction, and transmission, as well as the electrical activity of individual neurons in many physiological phenomena, have greatly advanced the work that is central to the central nervous system, which is difficult to perform in vitro experiments. A powerful tool in physiological research. With the microelectrode
