Abstract
A diagnostic method is disclosed wherein brain evoked potential (EP) data from a plurality of electrode sites on the patient's head is gathered and compared with a comparable EP for normal patients by forming (1) the cross-correlation between the patient's EP and the normal EP, (2) the maximum cross-correlation for any time shift in a selected period or C.sub.max, and (3) the time shift T.sub.max at which the maximum correlation occurs. Selected ones of these values for particular evoked potentials are used to compute diagnostic feature values, and a plurality of diagnostic feature values are used to achieve a diagnosis of brain pathology.
