A Brainwide Map of mouse brain neural activity during decision-making was released by the International Brain Laboratory ( https://internationalbrainlab.org) and we want you to use it to test your own hypotheses! At the Society for Neuroscience meeting this year, we will host a workshop for anyone interested in learning to use the data. During this tutorial we will teach you to search and download datasets, do basic analyses, and give tips for more advanced computation. We will also demonstrate how to upload your analysis results to our visualization website. Bring your laptop to work along with the demonstration. Participation is free, but registration is required.
