Ultra small (~13cm tall) 12 Channel Commutator for INTAN and UCLA3 & 4 Miniscopes.
It has a thru hole and mounting flange for optogenetics and fluid delivery.
The motorized commutator utilizes a magnetic hall-effect sensor which detects any
cable twisting when the animal moves. When twisting is detected the sensor signals
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 smallest high-quality economical
motorized commutator for Intan-based headstages and UCLA mini-microscopes (VS3 and 4).
