Details
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.
- 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 capabilities. 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)
