ABSTRACT:
A method and apparatus for suppressing epileptic seizures whereby an EEG electrical signal from an epileptic is amplified, filtered to remove components above roughly 8 Hz and below 2 Hz, and applied to a level detector which produces a trigger signal when the EEG amplitude exceeds a predetermined, variable level. The gated signal operates an oscillator to produce a signal which is in turn applied to a speaker, such as a set of earphones, to produce an audio signal which is maintained for as long as the seizure lasts, and then for an additional 4 seconds.
