abstract = {Adolescence is a period of dynamic brain remodeling and
susceptibility to psychiatric risk factors, mediated by the
protracted consolidation of association cortices. Here, we
investigated whether longitudinal variation in adolescents'
resilience to psychosocial stressors during this vulnerable
period is associated with ongoing myeloarchitectural
maturation and consolidation of functional networks. We used
repeated myelin-sensitive Magnetic Transfer (MT) and
resting-state functional neuroimaging (n = 141), and
captured adversity exposure by adverse life events,
dysfunctional family settings, and socio-economic status at
two timepoints, one to two years apart. Development toward
more resilient psychosocial functioning was associated with
increasing myelination in the anterolateral prefrontal
cortex, which showed stabilized functional connectivity.
Studying depth-specific intracortical MT profiles and the
cortex-wide synchronization of myeloarchitectural
maturation, we further observed wide-spread
myeloarchitectural reconfiguration of association cortices
paralleled by attenuated functional reorganization with
increasingly resilient outcomes. Together,
resilient/susceptible psychosocial functioning showed
considerable intra-individual change associated with
multi-modal cortical refinement processes at the local and
system-level.},
