Abstract

A method is described for simultaneous measurements of pO2 and action potentials with microelectrodes using prefabricated gold wires. The construction and measuring with such gold electrodes is easier than with traditionally used platinum electrodes. Single electrodes recording is done with a specially adapted electronic circuit, allowing the separation of both signals (pO2 and action potentials. A measurement in cat brain illustrates this procedure.

摘要

描述了一种使用预制金线通过微电极同时测量pO2和动作电位的方法。与传统使用的铂电极相比，这种金电极的构造和测量更容易。使用专门适配的电子电路进行单电极记录，可分离这两种信号（pO2和动作电位）。在猫脑上的测量说明了该过程。
