Rodents have an orientation map of their surroundings, produced and updated by a network of neurons in the entorhinal cortex known as 'grid cells'. However, it is currently unknown whether humans encode their location in a similar manner. Using functional magnetic resonance imaging in humans, a macroscopic signal representing a subject's position in a virtual reality environment is now detected that meets the criteria for defining grid-cell encoding.
