High Performance Electrophysiology Recording & Experiment Control
Cheetah 5 was replaced by Cheetah 6, October 2016. You may wish to upgrade to the latest version. Please note: Cheetah 160 acquisition systems are not supported on Windows 7. Digital Lynx SX acquisition systems require Windows 7 or higher. Digital Lynx S acquisition systems require a DIP switch change when upgrading from Cheetah 5.4 and earlier versions to Cheetah 5.6.3.
Over the past 20 years, Neuralynx has been continually developing and enhancing Cheetah Software for Single Unit Action Potential and LFP research experiments, providing the signal and data processing features and performance required for this highly demanding aspect of neuroscience research. Cheetah enhancements support the flexibility to easily configure electrode input channel assignments and signal processing options needed for the user’s specific experiments.
One software package - Cheetah 5.0 - seamlessly integrates with Neuralynx’s hardware acquisition subsystems, including Cheetah 160, Digital Lynx S, Digital Lynx SX, Digital Lynx SX-M and Digital Multiplexing Headstages.

Acquisition Entities & Display Properties
Neuralynx’s Digital Lynx SX system eliminates channel duplication challenges by digitizing and sending the signal to Cheetah without any analog domain modification: all channels are sampled at 24-bit resolution and are full bandwidth (DC to 8 KHz). Digitizing the full bandwidth signals allows Cheetah to perform digital filtering (Digital Signal Processing (DSP) on the signal. Users can make unlimited copies, or “clones,” of each input channel and use Cheetah to perform the desired bandwidth filtering for each signal type. Changes to the settings of an acquisition entity using one of the cloned channels will not affect any other acquisition entity using other clones of that channel. Note: The most common use of channel cloning is to record a continuous version of one tetrode channel, allowing the user to filter for low frequency signals, such as Theta, while still recording the high frequency spike activity without any special connections or equipment.
Cheetah manages all hardware settings “behind the scenes,” making Digital Reference Selection (DRS) set up easy. Instead of having to control each setting of the DRS hardware analog switch arrays – the interactions between the DRS functions and the input boards and with each other - the user merely sets the reference input for an acquisition entity (AE) directly in the AE property page.
Additionally, Cheetah eliminates manual programming of the references in a configuration file: the reference selection list only shows A/D Channels and dedicated references that the hardware is currently capable of using as a reference for a particular AE. Once a reference is selected, Cheetah programs the necessary hardware changes to set the reference appropriately.
Video Tracking Software (VTS) supports many modes, such as multiple “targets” for position, navigation, head direction and Grid cell experiments/studies.
Distributed data analysis and experiment control are supported by our NetCom library, enabling users to focus on developing custom analysis and control programs for their experiments without being concerned about the details of data acquisition engineering.
