title: A computer system for the analysis and synthesis of field potentials.
abstract: 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.
