Figure 2. Infant brain structural and functional development.
A) Visualizations of infant brain cortical surfaces at birth, 1 year, and 2 years of age. Large growth is clearly visible in terms of total brain size, cortical surface area, and cortical thickness Adapted from (Li et al., 2015). B) Resting-state functional connectivity network visualizations at birth, 1 year, and 2 years of age. The different lobes containing each region are labeled. Increasing separation of regions into functional modules spanning multiple lobes is apparent over this timespan. Adapted from (Gao et al., 2011). C) Community structure of 230 functional ROIs in 1–2 year olds (top) and in adults (bottom) using closely matched methods. Labeling of infant modules was informed via the adult set: Vis (visual), tDMN (temporal default mode network), pcDMN (posterior cingulate DMN), aDMN (anterior DMN), SMN (somato-motor network), SMN2 (somato-motor network 2), DAN (dorsal attention network), pFPC (posterior frontal parietal control network), aFPC (anterior frontal parietal control network), SubCtx (subcortex), CO (cingulo-opercular), pCO (posterior CO), and Sal (salience). Adapted from (Eggebrecht et al., 2017).
