title: [Spatial diffusion of action potential densities in a neural network: a heuristic model].
abstract: A continuous approximate stochastical diffusion model for some electrical activities in neural networks is presented. From the interspike interval distribution, which is governed by a Wiener-Markov process, a one-dimensional diffusion equation for action potential densities in the state space is deduced. These densities also depend on a diffusion equation which is defined on the three-dimensional euclidean space, at least for rather regular threshold distributions.
