Grid cells are cells of the brain’s internal map of space that fire when an animal is in a location corresponding to the vertices of a hexagonal grid pattern tiling the entire environment; how the pattern is mapped onto the external environment has remained a mystery, however, new studies in rat reveal that the axes of the grid are determined by the boundaries of the external environment and provide insight into the rotation of the grid axis in relation to these boundaries.
