Chie Satou explores how the brain carries out behavior in adult Danionella fish to understand distributed neural circuits underlying naturalistic behavior. Satou and her team investigate why animals behave in a certain way, model the behavioral strategies they have evolved, and look for neural circuits that produce these strategies. They use high-resolution automated movement tracking to explore the naturalistic behavior of Danionella fish and employ whole-brain neural recordings to study the brain-wide circuits underlying complex behaviors. By quantifying and modeling behavior, Satou and her team seek to make predictions about the kind of computational logic to look for in the brain.
