Adam M.P. Miller, William Mau, and David M. Smith found that spatial representations develop in the retrosplenial cortex (RSC) as rats learn a memory guided spatial navigation task. Spatial information is encoded in the form of population firing patterns, and, after learning, these firing patterns simulate future goal locations, suggesting an RSC role in navigational planning.
