Abstract

Abstract This article considers the problems encountered in the study of basic electrophysiologlcal properties of aged animal brain cells and describes several methods that are useful for such studies. Specific methods for rat brain slice preparations are reviewed, with an emphasis on factors relevant to aging animals. Alternative approaches (acutely dissociated cells) are also considered. Methods for investigating pharmacologically isolated and defined calcium potentials and calcium currents in aged rat brain neurons also are described. These may play an important role in the brain aging process.

脑神经元制备中钙电位和电流的衰老变化研究
本文就老年动物脑细胞基本电生理特性研究中遇到的问题进行了探讨,并介绍了用于老年动物脑细胞电生理研究的几种方法。综述了大鼠脑片制备的具体方法,重点介绍了动物衰老的相关因素。也考虑了其他方法(急性游离细胞)。本文还描述了研究老年大鼠脑神经元中分离的和确定的钙电位和钙电流的药理学方法。这些可能在大脑衰老过程中发挥重要作用。
