Extended Data Fig. 10: Weakly coherent place field rotations during remapping.

The increase in the median PF correlation (left), PV correlation (middle), and PF shift (right) are shown for 3 experiments: wall morphing without fish removal (Fig. 4i), wall morphing with fish removal (Fig. 5i), and wall morphing with landmark removal and fish removal (Fig. 6a). Blue dots show the comparison of session 1 and session 2 after registration of session 2 maps based on session 1 wall geometry and landmarks. Red dots show the comparison of session 1 and session 2 after registering session 2 maps to session 1 maps using the nonrigid transformation with the best rotation angle. Data from the same fish are connected by gray lines. The observed improvement in PF correlation from map rotation was evaluated by a non-parametric shuffle test (Methods), applied to each fish individually: wall morphing without fish removal (1/4 fish, p < 10−5, 3/4 fish, p ≥ 0.01), wall morphing with fish removal (1/3 fish, p < 10−5, 2/3 fish, p ≥ 0.01), and wall morphing with landmark removal and fish removal (2/4 fish, p < 10−5, 1/4 fish, p < 0.01, 1/4 fish, p ≥ 0.01). See Supplementary Table 1 for exact p-values.
