From local space to higher-order maps

Successful movement depends on an accurate sense of one's location within a particular environment. Neuroscientists distinguish self-centered and world-centered navigation and have been searching for a brain region where all ingredients of navigation come together. As rats foraged in an open field, LaChance et al. recorded activity from single neurons in an area called the postrhinal cortex. The authors found a population of cells that transform an animal's immediate sensory perception of its environment into a spatial map. This map is markedly different from the high-level representations observed in hippocampal place cells or entorhinal grid cells, but it is very flexible and is likely to provide the necessary building blocks for creating higher-level representations.
