FreeLynx (formerly Cube2)

Configurable wide bandwidth wireless digital acquisition system. 256 channel recording to on-board MicroSD memory. 128 channel wireless recording with reliable transmission up to 10 meters.

Very flat frequency response to accurately record both low-frequency Alpha and Theta oscillations, and high-frequency Single Unit Action Potentials.

FreeLynx utilizes a separate, customizable Analog Front End (AFE) interface that easily adapts to multiple FreeLynx standard configurations. This enables the user to optimize weight distribution, record from multiple implant sites, adapt to varying channel counts, or incorporate animal physiology sensors. With this technology, Neuralynx is able to rapidly develop custom AFEs – in 32 channel increments - to meet specified multi-site implant requirements.

Comprehensive line of accessories, including omni-directional video tracking LEDs and securely mounted self-aligning QuickClip® EIBs.

  • Option #1: Up to two FreeLynx can be used simultaneously with the Digital Lynx SX

    • Switch between two recording modes at any time:
      • record up to 256 channels to a FreeLynx onboard microSD card OR
      • wirelessly transmit up to 128 channels from each FreeLynx

    • Simultaneously record from any Digital Lynx SX input: FreeLynx, Combo Board, Input Board and HS-mux series headstages
    • Real-time signal processing with HPP
  • Option #2: Use Cheetah to directly control a FreeLynx without a Digital Lynx SX

    • Switch between two recording modes at any time:
      • Record up to 256 channels to a FreeLynx onboard microSD card OR
      • wirelessly transmit up to 128 channels from each FreeLynx

“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.”
