It is shown how field potentials due to neuronal membrane processes can be computed by means of a digital computer system. The essence of the method consists in evaluating a discrete expression for the field potential as a function of membrane potentials. This expression is considered as a three-dimensional convolution. In the computer system this convolution is performed by multiplication in the spatial Fourier domain. Introduction of a density function provides the possibility of evaluating in an easy way the field potential of a population of neurons. To demonstrate the applicability of the system, field potentials of different membrane potential configurations in the brain have been computed.
展示了如何通过数字计算机系统计算神经元膜过程产生的场电位。该方法的本质在于评估场电位作为膜电位函数的离散表达式。这个表达式被视为三维卷积。在计算机系统中，这种卷积通过空间傅里叶域中的乘法来执行。引入密度函数提供了一种简便方法来评估一群神经元的场电位。为了证明该系统的适用性，已经计算了大脑中不同膜电位配置的场电位。
