Data Formats

The datasets listed here are not guaranteed to be in any particular format. Whenever possible, using standardized data formats can help make datasets more inter-operable.

Standardized data formats for neurophysiological data include:

• Neurodata Without Borders, or NWB, is a general data standard for neurophysiology, with the goal of promoting a common standard for storing, sharing, and archiving data. The NWB project also maintains a list of publicly available NWB datasets.
• Brain Imaging Data Structure, or BIDS, is a set of data standards for imaging data, including MRI, EEG, MEG, and iEEG.

Repositories

There are several repositories, journals, and search engines that can be checked and searched for relevant datasets.

Neuroscience Specific Data Repositories

• OpenNeuro is a platform for analyzing and sharing neuroimaging data. Originally focused on MRI datasets, it now includes other modalities, including some electrophysiological data. Data on OpenNeuro is generally organized in BIDS formats.
• The DANDI archive ('distributed archives for neurophysiological data integration') is a platform for sharing and processing neurophysiological data. It includes a list of public datasets. Data on DANDI is generally organized in NWB format.
• The DABI repository ('data archive BRAIN initiative') is a platform for storing and processing invasive neurophysiological data, in particular for the BRAIN initiative.
• The EBrains platform for the European Union's 'Human Brain Project' includes a data portal with available data, including some extra- and intra-cranial human recordings
• CONP, the 'Canadian Open Neuroscience Platform', is a resource for sharing open-science workflows and neuroscience data, including all kinds of neuroscience data.

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 data hosting of open-datasets for specific studies. It doesn't seem to be easily searchable by data modality in particular, but does host relevant datasets, 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 resources, and select 'type' as 'Dataset' to see available datasets.
• Dryad is a repository service for scientific datasets, and includes data linked to specific papers, including some EEG/MEG/ECoG datasets. There is a search function.
• G-Node Open Data is a repository service for scientific datasets, by G-Node (the German Neuroinformatics Node), built on the G-Node data infrastructure services.
• Harvard Dataverse is a general-purpose repository for research data, that includes some neuroscience data
• Science Data Bank is a general-purpose repository for research data, that includes some neuroscience data
• Kaggle is a private company that hosts data analysis competitions. These competitions typically include a dataset, and they also maintain a repository of available datasets.
• The IEEE Data Port is a general purpose repository managed by IEEE (the institute of electrical and electronics engineers). Some datasets are freely available, however some require a DataPort subscription. For neuroscience related data, see the biophysiological signal section.

Data Journals

There are journals that specifically describe openly available datasets, and/or mandate that data be openly released, including:

• Scientific Data
  • A general purpose journal that publishes brief reports on openly available datasets
• Data in Brief
  • A general purpose journal that publishes brief reports on openly available datasets
• GigaScience
  • A general topic journal that publishes papers for which all associated data must be made available
  • Data is uploaded to their GigaDB database, that is searchable
