Open Datasets in Electrophysiology

This is a list of openly available electrophysiological data, focused mainly on local field potential (LFP) type measurements from humans, specifically EEG, MEG, and ECoG/iEEG. This list is primarily maintained by Tom Donoghue.

A companion list of open tools is available here.


This list is curated by the VoytekLab, but all data is by and from external sources. We have not necessarily explored all of these datasets and offer no endorsement of ease-of-access and data quality, etc.

Everything listed here includes some openly-accessible data for research purposes, requiring, at most, registration for access. Be sure to check the license and/or usage agreements for any datasets you access.

Generally, what is described here are large scale collection projects, as well as any kind of dedicated databases for such data, including links to particular individual datasets of interest - though it doesn't necessarily list all individual datasets in a given database.

General Purpose Data Repositories

There are a few general purpose repositories that you can search for data:

  • Zenodo hosts datasets for individual studies. You can find available datasets by searching for 'eeg', 'meg', or similar, and selecting the 'Dataset' tag on the bottom left of the search page.
  • Open Science Framework is a platform for supporting open science, and includes, amongst other things, data hosting of open-datasets for specific studies. It doesn't seem to be easily searchable by data modality in particular, does does host relevant data, some of which are included in the listings below.
  • Figshare is a general repository service for a broad range of materials, and includes datasets. You can search for a data type, or other specifier, and the select 'type' as 'Dataset' to see available datasets.
  • Dryad is a repository service for scientific datasets, and includes data linked to specific papers, that is searchable, and includes some EEG/MEG/ECoG datasets.
  • Kaggle is a private company that hosts data analysis competition. These competitions typically release a dataset for us, and they also maintain a repository of available datasets.

Neuroscience Specific Data Repositories

  • OpenNeuro is a free and open platform for analyzing and sharing neuroimaging data. It is currently more focused on MRI datasetes, but includes at least one EEG-fMRI dataset, and may expand to include more electrophysiology data.

Data Journals

There are journals that specifically describe openly available datasets, such as Scientific Data and Data in Brief. Both of these are general purpose journals focused on publishing brief reports about openly available datasets (but do not host the data themselves).

There is also GigaScience, a general topic journal that publishes papers in which all associated data is uploaded to their database, GigaDB, that is searchable for specific datasets / datatypes, and does include some electrophysiology data.


If you know of a data source that is not listed here, let us know! To do so, you can open a Pull Request with the dataset added in to this file, or just open an issue and mention the dataset & link, and we'll add it in.

Also: if you have any trouble actually getting data from any of these sources, let us know, and we'll remove the listing.
