Abstract
Disclosed are a method and a system for determining if a patient's brain electrical activity reflects a significant evoked response to a sensory stimulus. A test measure of the difference between two sets of averaged waveforms, one in the absence and another in the presence of the stimulus, is derived on the basis of (i) mean values of spectral measures of the two sets and (ii) the variance of these spectral measures. This test measure is matched against acceptance and rejection levels which are defined on the basis of both (i) the number of averaged waveforms in each set and (ii) the desired degree of probability of avoiding false positive or false negative results.
