Résumé :

A method is described which allows the elimitation of eye blinks and other artifacts from the evoked potentials averaged from tape-stored EEG data. The method includes the reading at faster speed of the recorded tape in reverse (with respect to the initial record) into comparator and gate functions which write on a separate track a step function-during and before baseline shifts. The method consistently eliminates the inclusion of tape sections with spurious baseline shifts in the multichannel EEG samples subsequently averaged. © 1974.
