Abstract

A three-dimensional "cable" equation with reversal potentials is derived for an infinite syncytium. Its solution is found analytically by using Green's function methods for the special case of two impulsive conductance changes activated at different "points" in space. It is shown that junction potentials generated at different sites in the syncytium do not in theory sum linearly.

摘要

针对无限大的合胞体推导出了一个具有反转电位的三维“电缆”方程。对于在空间中不同“点”激活的两个脉冲电导变化的特殊情况，通过使用格林函数方法解析地求出了它的解。结果表明，合胞体中不同位点产生的连接电位在理论上并非线性叠加。
