Abstract: A method and apparatus is provided for controlling video and film games by a player's (22) bioelectrical signals (44) comprising the steps of displaying a sequence of visual images having a predetermined control signal (62), obtaining an electroencephalographic (EEG) signal (44) from the player (22) while the player (22) is viewing the display of visual images, analyzing the EEG signal (44) to determine its magnitude, sending a signal (60) to the player (22) when the magnitude falls within a range of values corresponding to an amplitude threshold voltage (66) thereby causing the player (22) to mentally concentrate on the display (40) and affect a change on the magnitude of the EEG signal (44) which changes the sequence of visual images being displayed in accordance with the change in magnitude.

Abstract: An improved method and apparatus for displaying and either inhibiting or promoting selected bioelectrical frequencies emitted by a living organism. The method includes the steps of detecting an analog bioelectrical signal, converting the signal to discrete digital signals representing corresponding frequencies and numerically analyzing the digital signals to determine the different bioelectrical frequencies emitted by the organism. Furthermore, a threshold amplitude associated with a selected digital signal can be established an auditory or visual signal can be sent to the organism to indicate whether the bioelectrical frequency under study is within or outside the threshold amplitude. With this information the organism can be taught to inhibit or facilitate the bioelectrical frequency.
