Abstract
A method is described by which electrolytically sharpened tungsten wires were coated with a coaxial assembly of 5-8 glass-capillaries. This glass coating provides good insulation and high rigidity of the tungsten electrodes. The glass pipettes were used for electrophoretic ejection of test substances and the tungsten electrode for extracellular recording of neuronal activity.
摘要
本文描述了一种方法，通过该方法可在电解锐化的钨丝上涂覆由5 - 8根玻璃毛细管组成的同轴组件。这种玻璃涂层可为钨电极提供良好的绝缘性和高刚性。玻璃微吸管用于电泳喷射测试物质，而钨电极用于细胞外记录神经元活动。
