Abstract We have presented (Holden and Rubio, 1976) a model for flicker noise in nerve membranes in which there are interactions between adjacent ionic channels. These interactions are proposed to be mediated by order-disorder transitions in the membrane matrix. In this paper we explore the relaxation behaviour of our model, and, using transition state theory, predict a new class of membrane ionic currents which we call retardation currents. Such retardation currents have slow (hundreds of ms) kinetics, a low temperature dependence and appear as inactivation processes. We consider some candidate retardation currents.
