Variation of the 3D grid representations during volumetric navigation. a, c, e Three different pitch angle distributions with s.d. = 10°, 25°, and 75°, respectively. b, d, f Rate maps of the same neuron for the three different trajectory statistics. g The distribution of the FCC score of neural representations for the three different trajectory statistics (color coded as blue (for pitch distribution with s.d. = 10°), yellow (for pitch distribution with s.d. = 25°) and green (for pitch distribution with s.d. = 75°)). It is evident from the distribution that as the pitch angle range increases, the grid representation moves closer to the FCC regime. h Firing field of a neuron that shows maximum FCC score (~0.8). The firing fields are presented with three different colors to show the ABC sequence present in the grid representation which is a unique feature of FCC lattice structure
