Abstract

We describe a modified Hamilton microsyringe that allows extracellular recording of neuronal activity and subsequent injections. It is assembled with a Hamilton removable needle and a syringe for injection, a Teflon-coated tungsten wire for recording, and polyimide tubing as a sheath. The device is inexpensive and easy to handle in anatomical and physiological experiments in awake monkeys.

摘要

我们描述了一种改良的汉密尔顿微量注射器，它可用于细胞外记录神经元活动并随后进行注射。它由一支汉密尔顿可拆卸针头和一支用于注射的注射器、一根用于记录的聚四氟乙烯涂层钨丝以及作为护套的聚酰亚胺管组装而成。该装置价格低廉，在清醒猴子的解剖学和生理学实验中易于操作。
