A modular, scalable, multichannel neural data acquisition system with superior features and performance

Key Features

The alphaRS data acquisition system is a complete platform for conducting multichannel electrophysiology experiments. The system is modular and scalable with options to add on extra features and channels.

 

  • The system offers channel expandability
  • Digitized Headstages: Ultra-small and lightweight headstage suitable for all types of setups and subjects
  • Plug and play system: Suitable to be used with a variety of headstages ie. Intan, Neuronexus, OpenEphys, and more
  • Online statistics: Spike raster, firing rate, PSTH and evoked potential
  • Integrated Recording and Stimulation in one system: Using one software to control all channel’s modes and enabling closed-loop actions with short latency timing.
  • Advanced stimulation allowing a variety of stimulation options, patterns, and amplitudes, allowing manual or automatic control over all channel’s modes
  • Online Recording and Stimulation algorithm: An adaptive algorithm for fast recovery from stimulation artifact, the artifact deducted during stimulation enables online spike segmentation and sorting
  • Simultaneous data streaming of Raw, Spike & LFP
  • Real-time closed loop:DSP programming allowing fast response for closed-loop (>1ms)
  • Powerful DSPs: State-of-the-art Octa-core DSPs
  • SDK tool: Two-way communication using MATLAB or C++ for streaming all data and controlling system functionality
  • Built-in GUI for controlling various optogenetics systems

Complete MATLAB Control & Data Access

  • Data streaming. All data collected by the AlphaRS can be accessed online in MATLAB.
  • Full system control. From within MATLAB, commands can be sent to adjust almost all system parameters or trigger unique stimulation paradigms.
  • Closed-loop functionality. Data can be analyzed online, and results can directly trigger digital outputs or stimulation
  • Easy programming. Specially designed MATLAB toolbox and instructions make accessing data in MATLAB simple and easy.
  • Endless possibilities. Online access to data means each user can code paradigms specifically for their unique needs.
