Fig. 2: Sharp change at the time of birth across the perinatal trajectory of gyrification and its components.

From: Burst of gyrification in the human brain after birth

Fig. 2

Plot illustrating the regression discontinuity (effect size = 7.48, p = 6.44 × 10−14) of gyrification in (A), and the regression discontinuities of its components (surface area: effect size = 3.68, p = 2.26 × 10−4; and convex hull area: effect size = 1.26, p = 0.21) in (B) as a function of age at a cut-off of 37 postconceptional weeks (time of birth) (n = 819). In (A), red dots represent the fetal sample and cyan dots represent the postnatal sample, with a line indicating the time of birth. In (B), purple points represent the surface area trajectory, green points represent the convex hull trajectory, dots represent the fetal sample, triangles represent the postnatal sample, and the dotted line indicates the time of birth.
