title: A simple electronic unit allowing extracellular recording and stimulation through the same wire hook or suction electrode.
abstract: A simple and easily constructed unit was designed using a buffer amplifier, a programmable transconductance amplifier and an active filter. The unit allows extracellular recording and stimulation through the same electrode. Thus in experiments where it is required to stimulate a nerve and record the effects of the stimulation from the same nerve, the stimulating and the recording electrodes can be combined in one.
