摘要

为了研究受损背根节神经元的放电型式与其对钾离子通道阻断剂四乙基胺(tetraethylammonium,TEA)反应敏感性的关系,在大鼠背根节慢性压迫模型上记录单纤维自发放电。结果表明,具有混沌特性的非周期放电神经元比周期放电神经元对TEA反应敏感。

Abstract

In order to study the relationship between the firing patterns of injured dorsal root ganglion (DRG) neurons of rat and their sensitivity to tetraethylammonium (TEA), spontaneous activities from single fibers of chronically compressed DRG neurons were recorded.
