From: How do infant brains fold? Sulcal deepening is linked to development of sulcal span, thickness, curvature, and microstructure

Fig. 4: Curvature and microstructural changes in sulci during the first year of postnatal life.

a Curvature (CU [mm−1]) decreases logarithmically with age across all sulci in the first year of life. Each dot: mean CU per infant. Line: model fit. b, c Estimates of CU at birth (intercept) and rate of development (slope), calculated using a LMM relating mean CU to log10 (participant’s age in days). Error bars: standard error of the intercept and slope (N = 43 independent participants). d–f Same format as (a–c), shown for cortical microstructure (R1 [s−1]). Unlike CU, R1 increase with age. All data shown are from the left hemisphere (LH). RH data in Supplementary Figs. 3 and 4.
