Open Ephys

We develop and distribute open-source tools for neuroscience research

Open Ephys

Open Ephys is an employee-owned cooperative based in Atlanta, Georgia, with team members distributed around the world. We partner with the Open Ephys Production Site in Lisbon, Portugal, to bring high-quality open-source tools to cutting-edge neuroscience research. Our mission is to advance our understanding of the brain by putting the tools we use to study it in the hands of the community.

Since our founding in 2014, we've grown from making it possible to build an entire extracellular electrophysiology rig from off-the-shelf components to developing a broad ecosystem of popular hardware and software designs, now in use at more than 230 research institutes and pharmaceutical companies across 42 countries. As a cooperative, our ownership structure guarantees our designs will always be open-source, and we're excited to keep pushing science toward a more open future.

Contribution Guidelines

We use GitHub issues for bug reports and feature requests. Code and hardware contributions can be made via pull requests. If you are new to Git, please refer to this guide as a starting point. Feel free to reach out on Discord if you have questions!

Community Guidelines

We follow the Open Hardware Makers Community Guidelines. Violations may be reported to the Open Ephys team at info@open-ephys.org. All complaints will be reviewed and investigated and will result in a response deemed necessary and appropriate to the circumstances. The team is obligated to maintain confidentiality with regard to the reporter of an incident.
