A system and method for analyzing electrophysical signals produced by a brain involves comparing a first selected one of the numerical values to control data including one of a self- norm and a population-norm associated with electrophysical activity in a brain region corresponding to a brain region of origin of the electrophysical activity on which the numerical value is based; calculating a standard score for the brain region of origin based on the comparing; and repeating the comparing and calculating operations for a second selected one of the numerical values, the regions of the brain including subcortical regions extending to a brain stem of the brain.
