19. Summary A dynamical approach of brains and behaviors to capture complexity and nonlinearities in social behavior. A work in progress to characterize the spatio- temporal organization of brain states contributing to social interactions, especially during information-rich transitions. A mechanism for synchronizing brains and behaviors.
