前言在电生理学的研究中,为了研究组织深部(如脑组织)或单个细胞的电性活动,必须把微小的电极插进组织深部或细胞内,以便测量组织深部或细胞膜内外的电势差,这种电极称为微电极。微电极的大小没有明确的范围,是以对细胞的损伤减小到最低限度为原则,根据研究对象而定的。例如,当对乌贼的巨大神 Introduction In the study of electrophysiology, in order to study the electrical activity of deep tissues (such as brain tissue) or individual cells, tiny electrodes must be inserted into deep tissues or cells of the tissues in order to measure the potential difference inside or outside the tissue Electrodes are called microelectrodes. The size of the microelectrode is not a clear range, based on the principle of reducing the damage to the cells to the minimum, according to the research object. For example, when on the huge god of squid
