Abstract:
A method for producing a desired brain state in an individual by measuring and controlling a brain signal comprising;measuring a brain signal indicating a brain state of an individual; comparing characteristics of the measured brain state to characteristics of a desired brain state to determine the difference between the measured brain state and the desired brain state; selecting a magnetic field having at least one parameter selected from the group consisting of magnet position, field magnitude, pulse frequency, and pulse train duration to alter the brain state, wherein the at least one parameter is selected to most reduce the gap between the measured and desired brain states; applying the selected magnetic field to the brain of the individual; measuring a brain signal indicating the altered brain state, the altered brain state corresponding to the application of the magnetic field; comparing the characteristics of the altered brain state to characteristics of the desired brain state to determine the difference between the altered brain state and the desired brain state; and repeating the selecting, applying, and measuring a brain signal indicating the altered brain state steps until an acceptable brain state is achieved.
