Commutators
Electrical and hybrid commutators that untwist cabling for freely-moving recording.
Commutators
Slip-ring and active commutators for multi-channel electrical signals, keeping tethers untwisted during freely-moving behavior.
Commutators — FAQ
When and how to add a commutator to a recording setup.
Do I need a commutator?
Only for freely-moving recording — it untwists the tether as the animal turns. Head-fixed and acute setups do not need one.
Electrical vs. hybrid commutators?
Electrical commutators pass multi-channel signals; hybrid models add optical or other channels for combined optogenetics and recording.
How many channels can it carry?
Channel capacity depends on the model — match it to your headstage and acquisition channel count.
