  • Real-time stimulation artifact suppression for simultaneous electrophysiological electrical stimulation and recording
    Patent number: 10136832
    Abstract: A system and method of suppressing stimulation artifacts when performing electrophysiological electrical stimulation and recording. An artifact waveform is captured associated with a stimulus output, and then the artifact waveform calibrated during another stimulus output for accurately representing the actual artifact waveform received within each measured response to a stimulus. During actual stimulus generation and response recording, the calibrated artifact waveform is subtracted in at least one of the amplifier stages so that the artifacts are removed from the amplified response to the stimulus thus providing an accurate output without saturating the amplifiers.
