NAT Device - Wireless EEG Recordings in Rodents Spécial

The “NAT” (Neural Activity Tracker) is a multi-purpose data sensing and recording device that is extremely small, lightweight, and enables data acquisition for days to weeks, dependent upon programmable settings.

The NAT is a versatile and very compact device and its use for EEG and sleep studies, local field potential recording and behaviorally relevant event-related brain activity is proven.

It is a 4-Channel, wireless, 1KSa/sec Biosignal Data Recorder with 3-D Accelerometer and Infra-red Time/Event stamp Function. 

It’s miniaturized size, 18x22mm, less than 10mm in height (primarily due to the battery module, as the major part of the device has a profile of less than 4mm), and light weight, less than 2.2grams, makes it attractive in applications where regulatory constraints apply (mice).

The NAT device comprises of 3 key components – an on board flash memory, a proprietary CPU and a proprietary MEMS (MicroElectroMechanical System) device for accelerometer. An optional infra-red time/event-code recording board can be easily added to the device to allow alignment of behavioral events with the EEG recording.

The NAT’s main features are:

Hardware

  • Robustness and reliability
  • On-board clock (calibration/synchronisation with ext devices)
  • Reliable battery fitting (zinc-air cell)
  • Large 4GB memory (optional 8GB)
  • Programmable sample frequency
  • Advanced accelerometer for 3D movement detection
  • Infra-red Time/Eventstamp Function (optional)
  • On-board functionality indicator (LED)
  • Programmable start function for delayed onset
  • Recording of 2x2 channels via independent ground
  • Refreshable memory
  • Programmable AC input range p to +/-3.75mV; band pass filter 0.3-500Hz

Data Handling & analysis:

  • Connector compatible with USB2 for download
  • Connector compatible with USB2 for download
  • Accelerated data download (single/multi-device docking station
  • Easy data transfer (to Excel or similar), multiple/flexible data formats (incl. txt and csv format) 
  • Link to existing data analysis software

Battery

A specially designed gold-plated metal holder houses a single zinc-air cell: such cells are widely used in hearing aids, hence commercially available and easily replaced by the user. These batteries have an active power-delivery life-span up to two weeks allowing for long-duration continuous power. Battery replacement is easy and can be done by the user!

Optional I.R. Data-Coder

This extremely small add-on allows recording of an infrared pulse code along-side the analogue channels and accelerometer. 

Docking Station & Data Handling

The NAT device is provided with a single-channel docking station, including software, for download of data from flash via USB. A multiple docking station will soon be available. Once downloaded, the data are available for further processing in .txt, .csv and edf standard!

    Biosignal data acquisition & recording is becoming increasingly important in many applications, such as Biomedical and Neuroscience.

    The use of devices to record EEG (Electroencephalography) is of particular interest. Traditionally, these measurements are taken with tethered devices in the clinic, are short lasting and conducted in artificial settings.

    The ability to perform ambulatory monitoring of subjects provides the possibility of long-term data capture of bio-parameters in a normal living-condition or work-place. This has been an aim for many decades. In animals, these are difficult to reproduce and freely moving rodents/mammals are spatially limited to small arenas.

    The “NAT” (Neural Activity Tracker) is a multipurpose data sensing and recording device that is extremely small, lightweight, and enables data acquisition for days to weeks, dependent upon programmable settings.

    The NAT is a versatile and very compact device and its use for EEG and sleep studies, local field potential recording and behaviorally relevant event-related brain activity is proven.
