Abstract
The rapid automatic examination and evaluation of large numbers of subjects by electroencephalography is accomplished by removably securing electrodes to the head of each subject under test to provide a plurality of channels of brain wave information corresponding to different head regions. The brain wave signals are amplified, converted into digital form, and the relative power in each of a plurality of frequency bands for each head region is automatically compared with a set of comparative relative power data derived from a normal population by computing a Z-transform. The results of that comparison are then displayed.
