Claim One:
1. An EEG (electroencephalograph) system comprising: (a) a plurality of EEG electrode means adapted to be removably connected to the scalp of a subject to detect the subject's brain waves; (b) amplification means connected to the EEG electrode means to amplify the detected brain waves and produce an amplified signal output for each EEG electrode means; (c) a three-axis translation accelerometer adapted to be removably positioned on the head of the subject to detect the subject's head movement, the accelerometer producing at least one signal output indicative of the head movements; (d) an interference canceler connected to the outputs of the amplification means and the accelerometer signal output, the canceler comprising a filter having an output and an adder connected to the output of the filter and the amplification means, the adder producing corrected and usable EEG signals.
