Abstract

Electrophysiological properties of isolated dorsal root ganglion neurons from adult rats were studied by intracellular microelectrodes. All investigated cells were separated into two groups according to the duration of their action potential and the shape of its falling phase. The calcium component of the action potential could be separated by placing the cells into sodium-free, calcium- and TEA-containing medium. The presence of this component was revealed in all studied neurons.

摘要

采用细胞内微电极研究成年大鼠离体背根神经节神经元的电生理特性。根据动作电位的持续时间及其下降相的形状，将所有研究的细胞分为两组。通过将细胞置于无钠、含钙和四乙铵的培养基中，可以分离出动作电位的钙成分。在所有研究的神经元中均发现了该成分的存在。
