The motorized commutator utilizes a magnetic hall-effect sensor which detects any cable twisting when the animal moves. When twisting is detected the sensor signal a controller board which activates a motor to adjust the commutator in the appropriate direction to untwist the cable. These systems are designed specifically to be sensitive for mice and rats. NeuroTek is excited to produce the only commercially available motorized commutator which permits fluid delivery during electrophysiology
