Abstract

A new approach for the whole-cell recording in slices is suggested as simpler and less expensive one than those known before. Electrophysiological characteristics of excitatory postsynaptic currents are obtained. Two types of glutamate receptors are shown to be involved. The kynurenic acid is proved to exert more prominent effect on the NMDA-receptor mediated current. Biphasic action of adenosine, a wide spread neuromodulator, on synaptic transmission is shown.

[利用改进的电位固定法分析大鼠海马切片突触传递]。
提出了一种新的切片全细胞记录方法,这种方法比以前已知的方法更简单,更便宜。获得了兴奋性突触后电流的电生理特征。有两种类型的谷氨酸受体参与其中。结果表明,犬尿酸对nmda受体介导电流的影响更为显著。腺苷是一种广泛分布的神经调节剂,它对突触传递具有双相作用。
