A statistical study of the dynamics of the voltage membrane in protozoa Euplotes vannus

We consider the dynamics of the membrane voltage of Euplotes vannus and we suppose that behind this behaviour there is a system that generates Stochastic Resonance phenomena (Benzi R, Sutera A, Vulpiani A. J Phys A 1981;14:L453). We observe the statistical distributions of the resident times in the polarised and depolarised states. The experimental data are compared with the results obtained by an analogue device that simulates a model that gives an Autonomous Stochastic Resonance Process.
