Fig. 4: Fields were less numerous in the lattice mazes but larger in volume.

Source data are provided as a Source Data file. Markers in boxplots represent fields. Omnibus test results can be seen in Table 1; post hoc test results are displayed here: *significant at the 0.05 level, **significant at the 0.01 level, ***significant at the 0.001 level. a Schematic demonstrating the process of place field detection and analysis. An example firing rate map (left) is thresholded at 20% of the peak firing rate and regions which passed our criteria were considered place fields (second plot). We can visualize these regions as convex hulls (third plot) and extract features such as their centroid (right plot). b Aligned lattice maze schematic and place field convex hulls of four example place cells exhibiting 1–4 place fields. c Number of place fields exhibited by place cells in each maze. Inset: same data in boxplot representation. d Number of fields per cubic meter exhibited by place cells in each maze. e Distribution of place field volumes observed in each maze. f Enclosing diameter of place fields in each maze.
