Dear colleagues - The International Brain Laboratory <https://www.internationalbrainlab.com/> is entering a new phase. We have completed our "Brain-wide Map <https://www.nature.com/articles/s41586-025-09235-0>" of neural activity during a complex behavior, alongside detailed studies of the reproducibility of neural <https://elifesciences.org/articles/100840> and behavioral <https://elifesciences.org/articles/63711> data and the development of new methods <https://www.nature.com/articles/s41592-022-01742-6> and visualizations <https://viz.internationalbrainlab.org/app> for large-scale datasets, as well as many scientific studies <https://www.internationalbrainlab.com/publications>. Now, the IBL seeks to broaden access to its tools, pipelines, and methodologies to new research groups. You can now collaborate with the IBL on your own project: we aim to bring our approaches to new large-scale projects and we are looking for new partners! We can help with your Neuropixels recordings, multiphoton imaging, data processing, visualisation, data management, and more. Or, we can support work that you want to do using IBL's existing public data, for example if it requires running new large-scale analyses of those data that you need help with. These services are free to you, thanks to generous funding from the Simons Foundation, and provided by our world-class team of expert staff. Learn more and apply, with a short 2-page proposal, at: www.internationalbrainlab.com/ibl-core-apply Applications deadline now extended to Nov 8!
