Automatic artifact rejection during intraoperative recording of somatosensory evoked potentials. Technical note.
A device is described that performs automatic artifact rejection for somatosensory evoked response analysis in intraoperative and other electrically noisy environments. Although based on amplitude discrimination, rejection is not triggered by the large stimulus-dependent voltage transients associated with somatosensory evoked potentials. The device readily interfaces with commercially available evoked potential equipment.
