iBehave Network brings together exceptional experimental biologists, neuroscientists, computational biologists and clinician scientists from the Rhine area who will work across disciplines and species to study behaviors relevant for survival, and their underlying neuronal networks. We will use novel approaches for fine mapping of natural behaviors using machine learning and AI and combine them with emerging methods to record from large numbers of individual neurons in behaving animals and humans. Using computational and comparative approaches, we will develop a theoretical framework of behavior across species. Establishing joint technology platforms will make cutting-edge approaches available to record neuronal activity, map behavior with unprecedented precision, and share data within and outside the network. Junior Scientists within the network can take full advantage of the vibrant research community, benefit from the value of joint knowledge, resources and the state-of-the-art facilities for theoretical and practical training. By investing in a long-term joint strategy, we expect iBehave to have a lasting international impact in the fields of neurosciences, computer sciences and medicine.
