Where in the brain is outside space represented? In the mammalian brain, quite clearly it is represented multiple times, and with some differences from species to species. A remarkable representation, however, is that by grid cells, discovered in 2005 in rodents, in the medial entorhinal cortex. Subsequently conjunctive grid-by-head-direction cells were also found, and a similar spatial representation has been observed in bats. This contribution briefly reviews its main features, and argues that it is likely a representation that self-organizes. If so, it is expected that its main properties will reflect those of the environment where the animal is raised.
