Claim One:
1. A method of measuring the electroencephalographic activity of at least two lobes of the brain of a human trainee and providing the trainee with a sensory signal in response to a combination of amplitude and the inphase activity of each of the brain lobes comprising the steps of: attaching electrical contacts to the head of the trainee, said contacts being disposed adjacent to at least two lobes of areas of the brain, and to a neutral area of the trainee's head; obtaining at least two signals from said contacts which correspond to each of said at least two lobes or areas of the brain; amplifying said at least two signals; filtering each of the signals to obtain output signals each within a defined frequency range; summing the in-phase signals of the defined frequency band of the amplified brain wave activity to produce a phase relevant measure of the trainee's brain wave activity; producing an auditory signal and modulating the volume of the auditory signal responsive to the amplitude and phase of the summed brain wave activity; and presenting to the trainee an audible signal which reflects the degree of phase parity and amplitude of the signals recorded from said at least two lobes or areas of the brain.
