A Directional spike plots for example head direction (HD) cells recorded in the square environment from POR (left; N = 34 cells), RSC (middle; N = 37 cells), and MEC/PaS (right; N = 30 cells). B Top-down schematic illustrating the three sessions of the AB experiment. C Normalized HD tuning curves for POR HD cells across all three sessions of the AB experiment. D Change in bidirectionality for POR HD cells between the A1 session and both the AB and A2 sessions (two-sided Wilcoxon signed-rank test, AB vs. A1: W = 1, P = 2.33e-10; A1 vs. A2: W = 118, P = 1.57e-3; AB vs. A2, W = 9, P = 3.84e-9). * indicates P < 0.05. E Comparison of the degree of firing rate modulation attributed to cue A or cue B for all POR HD cells recorded in the two-cue experiment (two-sided Wilcoxon signed-rank test, W = 49, P = 3.53e-5). F–H Same as (C–E) but for RSC HD cells (two-sided Wilcoxon signed-rank tests, bidirectionality: A1 vs. AB, W = 111, P = 1.41e-4; A1 vs. A2, W = 187, P = 0.012; AB vs. A2, W = 171, P = 5.62e-3; modulation index: W = 3, P = 7.28e-11). I–K Same as (C–E) but for MEC/PaS HD cells (two-sided Wilcoxon signed-rank test, W = 207, P = 0.62). Source data are provided as a Source Data file.
