Bootstrapped cumulative distribution of grid-place cell coherence scores (blue) for the least robust place cell replay events (p>0.5 vs hippocampal replay shuffle). The shaded area shows 1SD of the bootstrap. The x-axis shows grid-place cell coherence scores and the y-axis proportion of events. Inset: difference between the data and shuffle distributions. The data distribution did not show significantly higher grid-place cell coherence than the shuffle distribution (p=0.17, AUC test).
