Extended Data Fig. 5: Cross-correlation structure of periodic neurons across epochs.
a, Cross-correlation structure of cell pairs for the top 25 periodic neurons in the window during mental navigation (first panel), during the ITI (second panel), during the presentation of start and target landmarks (third panel), during MNAV error trials (fourth panel) and during MNAV left and right direction trials (two rightmost columns), all sorted according to the peak correlation lag in the mental navigation window. Top: monkey A and bottom: monkey M. b, Cross-correlation values averaged over the lag of −5 to 5 ms for data from mental navigation plotted against data from ITI (left) and from the image presentation window (right). Left panels: monkey A, right panels: monkey M. c, Correlation between cross-correlation values during mental navigation epoch vs ITI (left) and vs inference epoch (right) at various lags (left). Left panels: monkey A, right panels: monkey M. Red stars denote the significance of Pearson’s correlation at p < .05 with Bonferroni correction. d, Same as b but for sessions in which the neurons were non-periodic. e–g, Cell–cell cross-correlation analysis compared across model and neural data. Left, distribution of lags at which each cell pair’s cross-correlation peaked for model (e), monkey A (f) and monkey M (g). Right, cross-correlation structure of simultaneously recorded periodic neurons, rank ordered based on activity during the navigation epoch for model (e), monkey A (f) and monkey M (g).
