High Performance, Expandable Recording System with Closed Loop Processing
The Digital Lynx SX is our flagship data acquisition system, combining nearly three decades of electrophysiology innovations into one high performance research solution to serve your lab for decades to come. This system is highly configurable and upgradeable to fit your immediate research needs and budget while enabling you to scale channel counts through the addition of Combo Boards and integrate peripherals through a versatile array of I/O connections. With one complete electrophysiology system, you can record analog signals from nearly all existing electrode interfaces or silicon probe implants, record digitized signals from digital multiplexing headstages, and process wireless data!
Starting in 2020, each new Digital Lynx SX includes the Hardware Processing Platform (HPP) for real-time, closed loop, data processing and response for neuromodulation and other advanced experiment designs.

Real-time Closed Loop Feedback
Digital Lynx SX includes HPP, a built-in user-programmable processor for low-latency data 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.
See our HPP Page for more details, documents, downloads and Applications Project updates.More about HPP
Digital Lynx SX is a full bandwidth, DC-coupled recording system, preventing artifact and signal clipping, ending the need for gain adjustments, and 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).
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 is available in two chassis sizes with either 4 or 16 Combo Board slots. An additional expansion option allows connection of low-cost digital multiplexing (MUX) headstages. A second fiber Ethernet connection may be used to input data from up to two FreeLynxTM headstages (up to 128 channels each), enabling closed loop processing of wirelessly-recorded neural signals.

Extremely stable, user-friendly, high-performance software package backed by two decades of continuous development, Cheetah Software is the ultimate solution for neural signal processing, display, recording, and network data distribution for real-time distribution for experiment control and analysis. Required for usage of Digital Lynx SX.
Neuralynx animal interface devices include this unique feature, giving you a built-in method for reward stimulation, lighting LEDs, joint shock delivery, eye-blink detection sensors, microphone signals, unbuffered signal transmission, or complex stimulus control. Up to 250 milliamps can be carried by these lines and the nominal resistance is about 3 ohms per meter. All Neuralynx acquisition systems may take advantage of this feature, depending on the actual interface devices chosen for your experiment.
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.
Utilize a simple, lightweight, easy-to-use optogenetic stimulus solution: Halo Microdrives and Fiber Mounted LEDs (FLEDs). These devices incorporate an independently-adjustable light source into the microdrive as an additional shuttle, delivering consistent blue, green, amber, or red wavelengths without additional optical connections, patch cords, ferrules, or FORJ.
