COMMUTATOR PRO

Unrestricted High Fidelity Electrophysiology

Versatile, Active

Engineered for Precision, Trusted in Motion

Cross-Tech Integration

Simultaneously Supports Passive Probe X Neuropixels

The Pro line commutator supports advanced multi-probe applications, enabling simultaneous use of Neuropixels and passive probes. For example, deliver electrical stimulation through a passive probe while recording high-density neural activity with Neuropixels, facilitating integrated stimulation and recording for complex circuit analysis.

Torque Sensing

Easily Adapted, Highly Sensitive

The Commutator Pro can be driven by two flexible torque sensing options: an animal-side gyroscope or an integrated Hall sensor. Its onboard microprocessor continuously and instantaneously detects and compensates for cable torque generated by animal movement, ensuring stable recordings and naturalistic behavior.

Multi-Paradigm
Experimental Support

Enhanced Experimental Flexibility

The Commutator Pro can be optionally configured with a 5 mm inner diameter channel, enabling fluid delivery or optical fiber access during ongoing electrophysiological experiments and further enhancing experimental flexibility.

Highly Capable, Customizable

Tailored Support for Your Workflow
Dual mode: Neuropixels + conventional probe
Up to 4 Neuropixels ports
Customizable HDMI port: headstage, gyro sensing and IO
Up to 9 GPIO

Easy to Adapt, Zero Barrier

Plug-in, Attach and You are Good to Go
The custom-developed sensor cable is exceptionally lightweight (<1 g) and highly flexible, constructed with a 34 AWG wire bundle.

Designed for easy installation to existing headstage and cable configurations, the sensor cable can be glued to the headstage cable/implant.

Adapted effortlessly to your system—improving behavioral outcomes and supporting animal welfare without requiring modifications to established workflows.
With the Commutator Pro, you can easily perform complex experiments—like recording high-density signals with Neuropixels while delivering electrical stimulation through a passive probe in the same animal—all without the hassle of wire tangling.

Optogenetics and Pharmacology Ready

Optionally configured passthrough channel is available for experiments involving optical fiber or drug delivery tube.

Low-Noise Operation

Low acoustic noise: 32-35 dB SPL during operation.
No observable electrical noise, validated digital communication

Stress & Burn-in Tested

The Commuter Pro has been rigorously validated to ensure flawless communication with both Neuropixels and Intan headstages. Even under continuous movement, testing ran uninterrupted for more than 36 hours — delivering error-free performance you can rely on.

Effortless Setup

Mount on top of a behavior box using the under-mount system or use a wild range of camera mount accessories with the 1/4- inch screw socket.
