Abstract
The Omstein-Uhlenbeck neuronal model is investigated under the assumption t hat the amplitude of the noise is signal dependent. A linear approximation of the input-output transfer function is developed. Different types of depe ndencies of the noise on the signal are considered. The conditions are pres ented under which a substantial difference between transfer functions with constant and signal-dependent noise appears. An example for which the: tran sfer function yields contra-intuitive behavior is presented. (C) 2001 Publi shed by Elsevier Science B.V.
