Abstract
A new method is proposed for extracting morphological information from evoked transients under conditions of poor signal to noise ratio. A non-linear signal estimation procedure for analysing evoked transients is described. The method of analysis produces enhanced estimates of the evoked transient average and provides information on the variability associated with the apparently time-locked activity in the members of the ensemble of evoked transients. As an example we use evoked transients measured on the surface of the human cortex in response to sensory stimulation.
