Figure 2. Relationship between different grid-modules across geometrically different enclosures.

Figure 2

a, Ratio between scales of simultaneously recorded grid-modules, mean scale ratio 1.56, n=11 rats.b, Relative orientations of simultaneously recorded grid-modules peaks at 0° and 30° but includes intermediates (p=0.02; Binomial test). c-d, Simultaneously recorded grid-cells from two different modules maintained their relative orientation in squares, circles and a hexagon.e, Preserved relative orientations were not due to Earth’s magnetic field. Colours as in the lower part of (d). Dashed lines, larger grid-modules; solid, smaller scale.
