Traveling Waves of Excitation in a Firing Rate Model of a Neural Network
Recent experiments have studied waves of electrical activity propagating in various brain regions. Neural field models provide a mathematical framework for the theoretical description of this type of activity. In the mean-firing-rate approach, the activity of a continuously distributed neural network is modeled by an integral equation for the mean membrane potential. We discuss traveling wave solutions of this equation, and how they are influenced by the distance-dependent axonal propagation delay.
