96 Channel Motorized Commutator

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 to be specifically sensitive to rat
movement (though is sensitive enough for a mouse, if tethers are kept light weight and short)
NeuroTek is excited to produce the only commercially available motorized commutator
which permits fluid delivery during high-density electrophysiology monitoring. Currently, very
few studies have incorporated high-density electrophysiology with drug delivery. However,
the ability to test the impact of pharmacological manipulations on neural activity in-vivo permits
us to investigate how neural activity is impacted by protein synthesis, plasticity, and basic synaptic
transmission in-vivo.
