When an inhibitory visual stimulus is turned off, an increased rate of spike discharge is evoked which we term the "rebound response". This response exists as a part of different cell responses from the retina to the cortex. The rebound response, with its temporal dependence on stimulus parameters, has not been previously considered in models. Here we present such a model, and also show its dependence on stimulus duration and its turning off rate. The rebound response enables detection of temporal changes when a visual stimulus involves spatial changes. The temporal change detection is affected by the actual stimulus duration, which can also be seen as a cell memory operation.
