This subject-mounted, battery-powered, wireless headstage transmits neural signal data to your acquisition system or computer, setting your research free of restrictive tethers. Designed for exceptional performance, FreeLynx does not require the use of a faraday cage. Just secure it to your animal interface, connect the Cheetah acquisition computer, and start recording data. Very flat frequency response accurately records both low-frequency Alpha / Theta oscillations and high-frequency Single Unit Action Potentials.
FreeLynx is an incredibly configurable system, allowing inputs from small animal tetrode drives such as our Halo Microdrives, implantable headstages, or advanced silicon probes at one or multiple implant sites. Neural signals may be digitized by FreeLynx or by separate multiplexing headstages. Our battery sizes further optimize the system for desired weight and recording duration.

Quickly Adapt to Animal Interfaces
Using a separate, customizable front end input module, FreeLynx quickly adapts to your animal interface. With our custom LVDS tethers, FreeLynx is compatible with most major silicon probes, making FreeLynx ideal for non-standard animal models and complex behavior studies. Our customizable front end also quickly adapts FreeLynx to varying channel counts, multiple implant sites, and flexible mounting options.

Get A QuoteExceptional Telemetry for Larger Animal Models
Engineered especially for high-density, high fidelity acquisition, FreeLynx opens the door to outstanding neural data quality and quantity from each untethered subject and is especially well-suited for neural recordings using models of 400 grams body weight and larger.
- Strong wireless signal transmission range allows large arena for natural behaviors and performance nearly indistinguishable from wired systems.
- Animal- and experiment-specific enclosure options protect device and implant sites for long-duration studies.
- Compatibility with advanced neural probes for precise and multi-targeting of brain regions.
“Our lab has experimented with a number of wireless data acquisition systems for both rodent and primate electrophysiology. We are very pleased with the recording quality and overall performance of Neuralynx’s [FreeLynx] – which we find to be virtually indistinguishable from traditional wired systems. We would happily recommend this device for any researcher seeking a reliable and user friendly system for performing wireless electrophysiology recording.”
Carol A. Barnes, Ph.D. Director, ARL Division of Neural Systems, Memory and Aging, University of Arizona
Flexible Recording Modes
1. A Stand-Alone Acquisition System
FreeLynx is capable of connecting and transmitting neural data up to 256 channels directly to a Cheetah acquisition computer. Multiple Cheetah / FreeLynx systems allow simultaneous time-synchronized telemetry recordings.
- Reduced cost for startup labs
- Up to 256 channels per FreeLynx / Cheetah system
2. Combine with the Digital Lynx SX
For Digital Lynx SX labs, FreeLynx brings additional advanced electrophysiology capabilities.
- Simultaneous wired & wireless recording
- Record from 1 or 2 FreeLynx simultaneously, up to 128 channels each
- Process and respond to signals in real-time with HPP closed loop technology
3. On-board MicroSD Memory
Switch FreeLynx to a high-performance neural data logger at any time during experiment by recording to a tiny on-board MicroSD card (~0.5 grams). Storage capacity allows continuous, high-density neural recording for 24+ hours depending on battery capacity.
- Remotely switch between telemetric and on-board MicroSD recording at any time during experiment
- Improves battery life to increase recording duration
Surprisingly Small & Light for Rat Models
At 30 x 35 x 30 millimeters, 11.5 grams, the FreeLynx is very powerful for its size.
- FreeLynx: 11.5 grams
- Small battery: 6.8 grams
- 64-channel AFE: 3 grams
- Total: 21.3 grams
- QuickClip® to Halo Microdrives – low-profile for reduced head torque
- Or connect to Mini-Amp-64 (Cambridge NeuroTech) implantable headstage
- Backpack options further reduce felt weight by relocating battery & FreeLynx to animal’s center of mass
