Digital Lynx SX
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.
up to 512 channels, in increments of 32
40 kHz simultaneous sampling
24-bit A/D converters
DC to 8 kHz
Wide Input Range
±132 mV (AC), ±1 V (DC)
Closed Loop Processing
Real-time Closed Loop Feedback
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.

Theta Oscillation Detection
Sharp Wave Ripple Detection
User-Defined TTL Output Responses
Additional capabilities can be programmed via C/C++ or VHDL
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.
Digital Lynx SX Chassis Options
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.
Digital Lynx 4SX: 4 Combo Board slots - up to 128 channels
Digital Lynx 16SX: 16 Combo Board slots - up to 512 channels
Digital Lynx 4SX-M or 16SX-M support MUX headstages - up to 128 channels
Connect 1 or 2 FreeLynx (up to 128 channels total) - enables closed loop processing of wireless data
Highly expandable for stimulus and experiment control
Connects to Cheetah workstation(s) via fiber Ethernet connection
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.
high resolution, full bandwidth recording with unfiltered, raw data files
channel cloning and digital signal processing for LFP/EEG/EMG and spikes
auto thresholding for functional spike detection levels
high performance visual displays for spikes and EEG
real-time distribution for experiment control and analysis
additional software integration for auto-clustering, custom analysis and control
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.
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.
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.
