p599fig16.35 Data (a) and simulations (b,c) about anatomically overlapping grid cell modules.  (a) shows the anatomical distribution of grid cells belonging to different modules in one animal.  DV location (mm) vs postrhinal border.  (b) shows the simulated distribution of learned grid cell spacings from two stripe cell scales.  frequency (%) vs grid spacing (cm). mu = [1, 0.6].  (c) shows what happens when half the cells respond with one rate and half another rate.  (d) shows the same with three rates.  (e-g) show spatial maps and autocorrelograms of grid cells that arise from the different rates in (d).  [rate map, autocorelogram] vs  [score [1.07, 0.5, 0.67], spacing (cm) [23.58, 41, 63.64]].<BR>||
