Abstract

A mathematical model for evoked potentials is outlined. The model has been developed by considering phase synchronisation of the underlying neurological processes. Tbe model, consisting of an ensemble of uncoupled linear oscillators with a gaussian distribution of frequencies is shown to reproduce tbe typical response of PIOO visual evoked response. Tbe model structure is parallel in form and is considered to be pbysiologically realistic. It is also sbown that tbe calculated behaviour of tbe ensemble can be generated by a 2"" order linear differential equation with time varying coefficients, thus highlighting the fact that entirely different physical structures can generate identical responses.
