Implanted electrodes: cable coupler for elimination of movement artifact.
The wires in the recording cable are connected to stainless-steel tubes supported by a ball bearing. The tips of the tubes rotate freely in mercury-filled grooves connected to the recorder through stainless-steel screws. No attenuation or distortion of the signal appears on records obtained through the coupler.
