[HTML][HTML] More than the sum of its parts: a role for the hippocampus in configural reinforcement learning

K Duncan, BB Doll, ND Daw, D Shohamy - Neuron, 2018 - cell.com
People often perceive configurations rather than the elements they comprise, a bias that
may emerge because configurations often predict outcomes. But how does the brain learn to …
