Radiens ↗ 4 brings analysis into the app you record with. Watch a PSTH build while the session runs, see the spectrum on replay, and assemble filters without writing code.
Research use only. NeuroNexus products are for non-clinical research use and must not be used in human or veterinary medical procedures.
What's new#
- PSTH and Spectral tabs: event-locked histograms and time-frequency views, live or on replay, with image export.
- Visual Filter Builder: hardware and DSP filter chains built on the signal path and saved for reuse.
- Signal-quality metrics: a tighter set with a lookback window and a mean peak-to-peak amplitude measure, live at Pro.
- Updates in the app: Radiens checks for a new release and installs it on restart, on macOS and Windows.
It records from Smartbox and XDAQ systems and the SiNAPS System, with native probe models for NeuroNexus probes, SiNAPS and Neuropixels. On an earlier version? Moving to Radiens 4 is an upgrade, and an Application Scientist can set it up for your lab.
