Origine des courants ioniques dans les cellules biologiques
The cable model describes the electric behavior of a biological cell membrane. For positive membrane conductance its potential is stable. This model does not explicitly take into account diffusion effects. We show that if the diffusion of the different ionic species is taken into account, an instability can set in for a positive global differential conductance. The instability is then characterized by a spatial modulation of the membrane potential and the occurrence of ionic circulations.
