Abstract
A method and apparatus for evaluating physiological and behavioral functioning of predetermined regions of interest of the human brain by displaying topographical maps of measured information. Brain electrical activity and/or predetermined physical parameters are measured in association with selected neuropsychological tests, and the measured information is operated on by providing weighted output signals characteristic of physiological functioning of the regions of interest of the patient's brain. The resulting weighted output signals are plotted as a topographical map. The measured brain electrical activity and measured predetermined physical parameters are also compared and a conversion matrix developed based on data bases of measured information for normal and abnormal subjects.
