Fig. 2. Functional connectivity strength shows dissociable patterns of maturation across the sensorimotor-association axis.

a-d Functional connectivity strength (FC strength) developmental trajectories vary continuously along the S-A axis. Each line represents an individual region’s FC strength developmental trajectory (zero-centered), modeled using generalized additive models. Colors indicate the rank of a given region along the S-A axis. e–p The plots display the developmental trajectories for regions from three representative functional networks: the somatomotor (e–h), salience/ventral attention (i–l), and default mode networks (m–p). Regions in the somatomotor network generally show increasing FC strength through development. Regions in the salience/ventral attention network exhibit both increasing and decreasing FC strength with age. Regions in the DMN predominantly show decreasing FC strength during development.
