Two-compartment stochastic model of a neuron with periodic input

Abstract

A neuronal model made of two interconnected parts - a dendrite and a trigger zone - is considered under the action of white noise and periodic inputs acting on the dendritic compartment. It is shown analytically how the variability of the depolarization potential is decreased from the dendritic to the trigger zone for subthreshold behavior. These filtering properties of the model are also shown when a reset mechanism is included at the trigger zone compartment.
