Radiens: one platform, from recording to result.
Radiens is NeuroNexus's electrophysiology software — acquire, analyze, and curate spike, LFP, EEG, and ECoG data from most systems in one platform.
Acquire, analyze, curate — one platform.
Analyze
From a raw recording to a result that holds up: sorting, LFP, spectra, 3D views.
Curate
Judge which recordings are good enough, and keep a qualified dataset — quality and history intact.
Used in research institutions
Why Radiens?
Better science, with less friction — and more from every recording, every session, and every lab.
More from every recording
See a failing channel or a weak response while the session is live and you can still act — so fewer recordings are lost, and each one gives you more.
Work at a higher level
Read dense data as spatial, visual views and results that hold up — less time wiring scripts together, more confidence in what you publish.
Stay plugged in across the lab
Quality and history stay visible at every stage, for everyone — so a PI or lab director can see where the data stands without being at the rig.
“The Radiens Software is very user friendly for sure, and that’s a good thing. I like the online features of spike sorting and being able to see each neuron independently” — Post-doc, Salk Institute.
Sized for your lab.
Two tiers that back your work at its scale, each adding the tools to push the science further — plus Radiens Services for expert time, quoted to the job.
Radiens comes from NeuroNexus.
For twenty years, NeuroNexus has built the full electrophysiology stack — probes, instruments, and software — used in 1,000+ labs and cited in 5,000+ publications. Radiens brings that two-decade track record to the software.
Frequently Asked Questions
Is there a free version of Radiens?
Yes — Radiens Standard is free and permanent, and it produces publication-grade results, not a trial or demo. The paid Pro tier adds professional analysis, curation, and the scale a working lab runs on.
What is the Radiens electrophysiology platform?
Radiens is NeuroNexus's software platform for electrophysiology — it acquires, analyzes, and curates spike, LFP, EEG, and ECoG data from most major systems in one place, and your data stays on your own machine.
Which company makes Radiens?
Radiens is made by NeuroNexus, which has been building the full electrophysiology stack — probes, instruments, and software — since 2004, used in over 1,000 labs and cited in more than 5,000 publications. Radiens brings that track record to the analysis software and is already in use at 100+ labs.
Is Radiens only for NeuroNexus probes and data acquisition systems?
No — Radiens reads data from most major electrophysiology systems (Intan, SpikeGLX, Open Ephys, TDT, Plexon, and NWB), not just NeuroNexus, so it fits your lab regardless of the hardware you record with.
Does Radiens work with open source software and files?
Yes — Radiens reads NWB, Open Ephys, and most common file formats natively with no conversion step, and interoperates with the open-source ecosystem through the free RadiensPy Python client.
Can Radiens be used with large datasets?
Yes — Radiens handles large-scale electrophysiology, working with high-channel-count recordings (1,024+ channels) and study-scale, multi-session datasets. The heaviest jobs run on your workstation today, with on-demand cluster compute in development for Radiens Compute.
