Figure 5:

Results of parametric bootstrap test performed on all pairs of regions to test if a significant conditional correlation exists between each pair of areas. Numbers inside the boxes are likelihood ratio statistics testing the hypothesis that $\left|D_{ij}\right|>0$. The colour of each box represents the results of significance tests for three values of $\alpha$, the false-positive rate, where each significance test is done with a Bonferroni correction for multiple comparisons. The level $\alpha =0.001$ is the smallest we are able to test given our simulation settings. The likelihood ratio values indicate that some pairs would be significant at much smaller values of $\alpha$. There are significant partial correlations between most pairs of areas at $\alpha =0.001$, except between DG and AM as well as between V1 and CA1.
