FC analysis between-group and within menstrual cycle phase (Left) and within-group (Right), using NBS after FC fingerprints reconstruction with 19 PCs (based on extent, cluster threshold = 4; α = 0.05; 5000 permutations). For each comparison, two representations are shown: a chord diagram with the edges that significantly differ (generated with NiChord Python toolbox (Bogdan et al., 2023)); four brain views showing the nodes that contribute to significantly different edges (generated with BrainNet Viewer MATLAB toolbox (Xia et al., 2013)); a bar plot in which each bar indicates the percentage of the total significant edges belonging to a network or inter-network connection (the bars are displayed in descending order of contribution, with only those contributing up to a cumulative 50% being included in the figure). For each comparison, the node size is scaled according to the node degree, which corresponds to the sum of the number of significantly different edges linked to that node. The networks are represented by colours, as indicated in the legend
