Abstract

The construction and operation of a simple device that produces varnish-insulated, high-impedance tungsten microelectrodes for single-unit recording is described. In essence, the device operates as a high-voltage pulse generator whose output creates an arc between a fully insulated tungsten microelectrode and a polished counter-electrode. As a result, insulation is removed reliably and symmetrically from the microelectrode tip. The device is constructed with a minimal outlay of time, skill, and money.

摘要

本文描述了一种简单装置的构建与操作，该装置用于生产用于单单元记录的漆绝缘、高阻抗钨微电极。实质上，该装置作为一个高压脉冲发生器运行，其输出在完全绝缘的钨微电极和抛光的对电极之间产生电弧。结果，绝缘层从微电极尖端可靠且对称地去除。该装置的构建只需花费最少的时间、技能和资金。
