Reconstruction of relative segment positions from theta dynamics depicted using 2D histograms that show both the actual and estimated positions. The colour-coded representations illustrate the probabilities of all possible combinations of actual and estimated positions. An ideal reconstruction outcome would manifest as a diagonal pattern. Left: during real-world navigation, the estimated positions (cross-validated) clustered closely around the actual physical positions within each segment. Middle: during imagined navigation, the estimated positions also aligned consistently with the positions estimated from the duration of the imagination periods particularly at the beginning and end of each route segment, illustrating heightened accuracy in those instances. Right: however, during sole treadmill walking where imagined navigation was absent, reconstruction failed to yield accurate results.
