Refractoriness - an overview | ScienceDirect Topics

Duration of refractoriness is an intrinsic property of each cell, and cells differ randomly according to a specified statistical distribution. A stimulus introduced inside the array near the time and place at which many cells are still refractory but many have recovered can elicit complex perpetual percolation of sparks of excitation, referred to as 'wandering wavelets'.
