About NWB
Progress in modern science is enabled by data sharing. There are major obstacles, however, that limit the open exchange of data particularly in neuroscience, a field where many small laboratories are pursuing diverse questions about the brain using a greatvariety of tools and techniques. In mid 2014, The Kavli Foundation initiated Neurodata Without Borders, a consortium of researchers and foundations with a shared interest in breaking down the obstacles to data sharing.
Overview
The aim of Neurodata Without Borders is to standardize neuroscience data on an international scale. Our goal is to break down the geographic, institutional, technological and policy barriers that impede the flow of neuroscience data within the greater scientific community. Our intent is to accelerate the pace of discovery and success of brain research worldwide.
The need to standardize neuroscience data has never been more urgent. Large-scale brain research projects such as the U.S. BRAIN Initiative and resources such as the Allen Cell Types Database are producing massive quantities of data. But the full benefits of these data will not be realized if they cannot easily be shared, pooled and analyzed.
NWB
Unlike in other fields (i.e. genetics and cell biology), neuroscience does not have a standardized way to collect and share the wealth of existing data among researchers. The lack of a common format has made comparison across laboratories difficult and replication of specific experiments almost impossible, significantly slowing overall progress in the field.
Neurodata Without Borders (NWB) is a data standard for neurophysiology, providing neuroscientists with a common standard to share, archive, use, and build common analysis tools for neurophysiology data. NWB is designed to store a variety of neurophysiology data, including data from intracellular and extracellular electrophysiology experiments, data from optical physiology experiments, and tracking and stimulus data. The project includes not only the NWB format, but also a broad range of software for data standardization and application programming interfaces (APIs) for reading and writing the data as well as high-value datasets that have been translated into the NWB data standard.
Neurodata Without Borders is intended to serve the broad neuroscience community and encourage the sharing of data by scientists worldwide. NWB 2.0 was released in February 2019. Please give it a try. Join our mailing list for updates or ask questions on our Slack channel.

Technical Design Goals of the NWB Format
Cross-platform
Support for tool makers
Quickly develop a basic understanding of an experiment and its
Review an experiment’s details without programming knowledge
Accommodate an experiment’s raw and processed data
Encapsulate all of an experiment’s data, or link to external data sources when necessary
Data published in the format should be accessible for decades
Accommodate future experimental paradigms without sacrificing backwards compatibility
Support custom extensions when the standard is lackingHistory
Launched in mid 2014, Neurodata Without Borders: Neurophysiology began as a pilot project to produce a unified data format for cellular-based neurophysiology data. NWB 1.0 was based on representative use case studies from four laboratories, and the project included a vetting phase for assessing whether other data models can also be used in the new common format. The initial development of NWB 1.0 was funded by industry and private foundations. Scientific partners include the Allen Institute for Brain Science (AIBS), the Svoboda Lab (Janelia), the Meister Lab (Caltech), the Buzsáki Lab (NYU), and Fritz Sommer/Jeff Teeters (UCB, maintainers of CRCNS.org). This one-year pilot project resulted in NWB 1.0.
Building on the success of NWB 1.0, the project entered a second phase, with additional leadership by Dr. Kris Bouchard, Dr. Oliver Rübel (Lawrence Berkeley National Laboratory, LBNL), Dr. Loren Frank (UCSF) and Dr. Edward Chang (UCSF). One main goal was to develop the next version of NWB and to enhance its adoption, through development of an advanced software architecture for NWB, a well-articulated data standards ecosystem, an open community software strategy, and advancements to the NWB data standard itself. NWB 2.0 was redeveloped by scientific software engineers/computer scientists at LBNL, Dr. Oliver Rübel and Mr. Andrew Tritt, in close collaboration with neuroscience laboratories and the broader NWB community. NWB 2.0 was released in February 2019 and new features continue to be added to the software ecosystem surrounding NWB 2.0.
The NWB project has also created a governance structure. An Executive Board (EB) decides the vision and roadmap for NWB and manages fundraising and outreach. The EB also works closely with a Technical Advisory Board (TAB), which makes technical decisions and maintains the software ecosystem.
We continue to see steady adoption of NWB:B by neuroscience labs, including the Allen Institute for Brain Science (AIBS), Bouchard lab (LBNL/UCB), Svoboda lab, Meister lab, Frank lab (UCSF), Chang lab (UCSF) and others. As labs adopt the format we also continue to see growing sets of data published in NWB. E.g, the AIBS has adopted the use of this format and to date has released numerous NWB files assaying mouse visual cortex.
