‘apparatus and Method for Remotely Monitoring and Altering Brain Waves Background of the Invention

[57] ABSTRACT Apparatus for and method of sensing brain waves at a position remote from a subject whereby electromag netic signals of different frequencies are simulta neously 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 represen tative of the brain wave activity is re-transmitted by the brain to a receiver where it is demodulated and ampli?ed. The demodulated waveform is then dis [56] References Cited played for visual viewing and routed to a computer for UNITED STATES PATENTS further processing and analysis.
