Explore how prior information about the world's state is represented across the brain in this neuroscience lecture examining brain-wide recordings from the International Brain Laboratory. Discover that prior information encoding occurs in 20-30% of brain regions spanning all levels of neural processing, challenging traditional models of where and how the brain incorporates prior knowledge. Learn about the implications of this widespread representation for understanding Bayesian inference in neural circuits, particularly how it supports models involving inter-area loops rather than localized decision-making processes. Gain insights into the neural mechanisms underlying cognition and the transition from sensation to action through this research conducted as part of the Simons Collaboration on the Global Brain initiative.
