Electrophysiology

NWB and BIDS together form the open data infrastructure for electrophysiology: BIDS organises EEG, MEG, and iEEG datasets using EDF and BrainVision as accepted file formats, while NWB is the rich single-file format for neurophysiology recordings. EDF is a widely used clinical EEG format. The IBL and the Allen Institute for Brain Science are major global producers of open neurophysiology datasets. G-Node is the German national neurophysiology and neuroimaging repository, offering long-term storage for electrophysiology recordings and spike sorting data. HED provides structured event annotation across both BIDS and NWB. Neo is an open-source Python object model and I/O library for reading electrophysiology data across a wide range of proprietary and open formats. EEG101 (COST Action CA24148) is a European initiative launched in 2025 to standardise EEG reporting, curate BIDS-compliant datasets, and promote open and rigorous EEG science through training and a community manifesto, with the Paris Brain Institute leading its working group on research culture change.
