Abstract :
A device is presented which utilizes a novel transistor switch for dc restoration of base line in neurophysiological recordings of impulse activity. A gate which operates the switch is derived from the initial rise of an impulse. The switch and associated circuitry allow only the impulses to pass and deliver no signal between impulses.
