Topographical mapping of brain functionality from neuropsychological test results
First Claim
1. A method of evaluating brain functionality of a subject comprising the steps of:
- providing neuropsychological test result data obtained from said subject in response to at least one preselected test;
generating a weighted matrix of test output signals by applying to said test result data a plurality of coefficients, each said coefficient being representative of said one preselected test and corresponding to a preselected region of the brain; and
displaying said weighted matrix of test output signals as a topographic map.

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.
