综述了单单元记录用金属微电极的电学性能。提出了一种等效电路，讨论了其构成元件。最重要的元件是由金属-电解质界面形成的电解电容器。其值约为0.2 pF/µ2at 1khz。描述了尖端金属暴露区和铂化的影响，并对这些电极在神经组织中的操作所特有的问题进行了一些考虑。
The electrical properties of metal microelectrodes for single-unit recording are reviewed. An equivalent circuit is presented, the elements of which are discussed. The most important element is the electrolytic capacitor formed by the metal-electrolyte interface. Its value is about 0.2 pF/µ2at 1 kHz. The effects of exposed metallic area at the tip and platinization are described, and some consideration is given to problems peculiar to the operation of these electrodes in neural tissue.
