Fig. 4. Differences in structural coupling for low (<33.3%), mild (33.3–66.6%), and high-stress-exposed infants (>66.6%).

Observations are the number of connections using different density thresholds with mean (black dots) and standard deviation (error bars). The orange line depicts structural coupling at a network sparsity of 20%. DMN default mode network, SN salience network. **P < 0.01, ns non-significant.
