Abstract: Mental abilities are labeled with terms such as memory & problem solving and corresponding performance measures (recall score, # correct) can be obtained. The quantitative EEG (QEEG) measure of brain functioning reflects the electrophysiology of the gray & white matter of the brain underlying the scalp. A database of clinical and non-clinical participants underwent a cognitive activation QEEG to determine the relations between the QEEG measures and cognitive performance for memory (auditory and reading) and problem solving. The analysis revealed correlative (positive and negative) relationships between cognitive performance and the Quantitative EEG (QEEG) measures (coherence, phase, magnitude, etc.) during these cognitive activation conditions. An individual can undergo an evaluation and the subject's values on the relevant (and all) variables can be determined. The deficient QEEG variables can be effectively changed with an operant biofeedback conditioning methodology called EEG biofeedback.

Abstract: Previous patents and research have focused on the problem of determining whether the quantitative EEG (QEEG) can discriminate a traumatic brain injury (TBI) subject from a normal individual. The patents and research have had varying degree of specificity in defining the variables involved in obtaining a high degree of discriminant ability. However, all research has limited its approach to the collection of eyes closed data and most confine themselves to under 32 Hertz. The present patent employs 4 cognitive activation tasks, an eyes closed task, 19 locations, the high frequency 32-64 Hz range (Spectral Correlation Coefficient (SCC) and phase algorithms) and frontal relative power of beta2 (32-64 Hz) to obtain 100% correct identification in a group of over 195 subjects (normal and traumatic brain injured (TBI)) across the 4 cognitive activation tasks and eyes closed condition. The approach is validated on a sample of 50 misclassified participants which the discriminant correctly identifies as misclassified.
