Fig. 6: Temporal consistency of IBAP anatomical location.
From: Heterogeneous, temporally consistent, and plastic brain development after preterm birth
Deviation scores for regional surface area (SA) were computed in preterm individuals with available longitudinal data using the bilateral Desikan-Killiany parcellation: a for preterm children from the ABCD cohort (n = 296) at ages 10 and 12 years and b for preterm adults from the BLS cohort (n = 46) at ages 26 and 38 years. Five representative regions are shown here; a complete representation can be found in Supplementary Figs. S14–S15. Only individuals who exhibited an extranormal deviation (i.e., infranormal: <5th percentile, supranormal: >95th percentile) at either timepoint are depicted. Within-subject comparisons demonstrate that the anatomical location of infranormal (blue) and supranormal (red) deviations remain largely consistent across time. Intraclass correlation coefficients (ICCs) were used to quantify temporal stability of regional deviations. Regional distributions of ICCs are shown on left hemispheric cortical surfaces for (c) preterm children and d preterm adults. See Supplementary Table S1 for region abbreviations. Source data and exact p-values are provided as a Source Data file (panels a, b) and in Supplementary Tables S4a, b (panels c, d).
