Sketch of the brain’s understanding system. Ovals in the blue box stand for neocortical brain areas representing different kinds of information. Arrows in the neocortex stand for connections, allowing representations to constrain each other. The MTL (medial temporal lobe, red box) stores an integrated representation of the neocortical system state arising from a situation. The red arrow represents fast-learning connections that store this pattern for later reactivation and use. Green arrows stand for gradually learned connections supporting bidirectional influence between the MTL and neocortex. A and B are two example inputs discussed in the text.
