| 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.

First Claim:
Show all 11 claims |
What is claimed is:
1. Brain wave monitoring apparatus comprising
- means 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, and
- means for interpreting said response signal.
