Digital Lynx SX

High Performance, Expandable Recording System with Closed Loop Processing

Schedule A Demo

Digital Lynx SX is highly configurable and upgradeable to fit your immediate research needs and budget: increase channel counts through the addition of Combo Boards and integrate peripherals through a versatile array of interfaces.

With the Digital Lynx SX, you can record neural signals as:

  • Analog signals with full configurable referencing from all from electrodes, including silicon probe implants
  • Digitized signals from our lower cost multiplexing headstages
  • Digitized signals from our FreeLynxTM telemetry acquisition module

Flat frequency response accurately records both low-frequency Alpha / Theta oscillations and high-frequency Single Unit Action Potentials. Each new Digital Lynx SX now includes the Hardware Processing Platform (HPP) for real-time, closed loop, data processing and response for neuromodulation and other advanced experiment designs.

Closed Loop Processing

 

Digital Lynx SX includes our Hardware Processing Platform (HPP), a built-in user-programmable processor for low-latency signal analysis and response (less than 1 millisecond). HPP can execute experiment stimuli with precise control of Digital Lynx SX analog and digital I/O: Combo Board inputs from buffered tethered headstages, digital multiplexing (MUX) headstages, FreeLynx wireless headstages, and TTL I/O.

  • Gamma Oscillation Detection
  • Theta Oscillation Detection
  • Sharp Wave Ripple Detection
  • User-Defined TTL Output Responses
  • Additional capabilities can be programmed via C/C++ or VHDL

Unmatched Signal Quality

 

Full Bandwidth Prevents Signal Clipping

Digital Lynx SX is a full bandwidth, DC-coupled recording system, preventing post-stimulus artifact signal clipping, ending the need for gain adjustments and switches – enabling continuous accurate recording during stimulus delivery with no recovery time even when inputs are saturated. This allows investigation of after-discharge signals and shows long-term DC electrode potential shifts without clipping (Brinkmann, 2009).

 

Extremely Flexible Referencing

Referencing is the key to improving your signal-to-noise ratio! The Digital Lynx SX provides extremely flexible reference selection with up to 8 references for each 32-channel Combo Board and 8 global references shared across the system. All references are software controlled, eliminating the need to physically change connections at the animal interface. Connections can also be changed on-the-fly to optimize signal quality during recording.

Cheetah Software

Required for use with Digital Lynx SX. An extremely stable, user-friendly, high-performance software package, Cheetah excels at neural signal processing, display, recording and network data distribution. Researchers can customize online experiment analysis and control, and process analog and/or digital data from up to 512 input electrode channels.

Differential Stim

Neuralynx animal interface devices (tethers, headstages and EIBs) include this unique feature, providing a built-in method for stimulation delivery, lighting LEDs, joint shock delivery, eye-blink detection sensors, and microphone signals through direct signal connections.

Video Tracking

All Neuralynx acquisition systems are compatible with our video tracking solutions, supporting position, navigation, head direction and grid cell studies with multiple targets. Video tracking data is synchronized with neural signal data by Cheetah Software, enabled through a separate VTS license.

Optogenetics

Halo Microdrives with Fiber Mounted LEDs (FLEDs) offer a simple, lightweight, easy-to-use optogenetic stimulus solution. The FLED is an optogenetic light source that is mounted as a shuttle in the Halo Microdrive to provide a depth adjustable stimulus light source. LED power is delivered directly through the Tether and EIB which eliminates additional optical connections, patch cords, ferrules or FORJ.

Configurations Documents

Digital Lynx SX amplifier chassis is available with either 4 or 16 Combo Board slots. The Combo Board’s MDR50 input connector receives signals from a vast array of analog interfaces and commutators to meet your implant type, mass, channels count and stimulus requirements. Each Combo Board digitizes up to 32 analog input channels at 24-bit resolution, with an additional 8 software-selectable references, 8 global references and 2 differential stimulus channels.

Digital Lynx SX may also be configured to input 16-bit digitized data from our lower cost multiplexing (MUX) headstages with the SX-M chassis option, or from FreeLynxTM telemetry modules with a WiFi router connection.

Additional configurations for optogenetics experiments, user-programmable low-latency processing and feedback, and external devices are available.
