Patent No. 5036858 Method and apparatus for changing brain wave frequency
Patent No. 5036858 Method and apparatus for changing brain wave frequency (Carter, et al., Aug 6, 1991) (RE36,348 Carter, et al., Oct 19, 1999) Abstract A method for changing brain wave frequency to a desired frequency determines a current brain wave frequency of a user, generates two frequencies with a frequency difference of a magnitude between that of the current actual brain wave frequency and the desired frequency but always within a predetermined range of the current actual brain wave frequency, and produces an output to the user corresponding to the two frequencies. One apparatus to accomplish the method has a computer processor, a computer memory, EEG electrodes along with an amplifier, a programmable timing generator responsive to the computer processor for generating the two frequencies, audio amplifiers and a beat frequency generator driving a visual frequency amplifier.
