Electrodiffusion Model of Rectangular Current
Pulses in the Ionic Channel of Cellular Membranes
Abstract
Ionic current pulses have been observed experimentally in a wide
variety of channels in the cellular membrane. These current pulses
are ``rectangular wave'' in shape and are distributed stochastically
in time. We will demonstrate the existence of stochastic-in-time
rectangular current pulses for a simplified electrodiffusion model of
the biological channel developed in analogy with the Gunn diode in
semiconductor physics.
