Apparatus and method for remotely monitoring and altering brain waves
First Claim
1. Brain wave monitoring apparatus comprisingmeans for producing a base frequency signal,means for producing a first signal having a frequency related to that of the base frequency and at a predetermined phase related thereto,means for transmitting both said base frequency and said first signals to the brain of the subject being monitored,means for receiving a second signal transmitted by the brain of the subject being monitored in response to both said base frequency and said first signals,mixing means for producing from said base frequency signal and said received second signal a response signal having a frequency related to that of the base frequency, andmeans for interpreting said response signal.

Abstract
Apparatus for and method of sensing brain waves at a position remote from a subject whereby electromagnetic signals of different frequencies are simultaneously transmitted to the brain of the subject in which the signals interfere with one another to yield a waveform which is modulated by the subject'"'"'s brain waves. The interference waveform which is representative of the brain wave activity is re-transmitted by the brain to a receiver where it is demodulated and amplified. The demodulated waveform is then displayed for visual viewing and routed to a computer for further processing and analysis. The demodulated waveform also can be used to produce a compensating signal which is transmitted back to the brain to effect a desired change in electrical activity therein.

9. A process for monitoring brain wave activity of a subject comprising the steps of
transmitting at least two electromagnetic energy signals of different frequencies to the brain of the subject being monitored, receiving an electromagnetic energy signal resulting from the mixing of said two signals in the brain modulated by the brain wave activity and retransmitted by the brain in response to said transmitted energy signals, and, interpreting said received signal.
