Abstract
A new method for evaluating the recovery function of evoked potential (EP) in real time was reported. To record the test response of paired stimulation, the responses to alternate presentation of unpaired stimulus and several kinds of paired stimuli with various interstimulus intervals were averaged respectively and subtraction was made in real time. The EP's to the test stimulus obtained by the proposed method were proved to be accurate even under the changing recording conditions. A formula for computing the recovery correlation factor was derived as a measure of the recovery function of the recorded EP, and the recovery curves for three subjects were obtained.
