Figure 1. Identical place field translation.
Stepwise horizontal linear translation of identical, overlapping place fields (N = 17, σ = 3) moving from the center to the right (A, C). EMD score is shown on the left while Pearson’s r is shown on the right (top panel - EMD vs Pearson). 12 steps are shown and scores are rounded for display. Scores from remapping tested at all possible centroids along a single row on the rate map (bottom panel). EMD and Pearson’s r scores tested at all possible centroids in the rate map (N*N) (B, D). Scores for horizontal and diagonal translations along the rate map are shown for all rows (N = 17) (top panel). Heatmap showing the gradient of scores for both raw and inverted EMD (left and center) and for Pearson’s r (right) (bottom panel).
