Abstract

A method of modelling evoked potentials in the multielectrode case, using the Prony´s method, is proposed and tested on the human cerebral responses. The multichannel model is derived from the state-space representation of a single-input multi-output system according to the linear systems theory. The evoked potential is considered as an impulse response of a linear system. The Prony´s method is chosen, to estimate the model coefficients, for its ease and speed. To estimate correctly the visual evoked potential model, with this approach, only 100 ensemble averages are needed
