The human brain is organized as segregation and integration units follows complex developmental trajectories throughout life. cortical manifold provides a new means of studying the brain’s organization in multidimensional connectivity gradient space. However, how morphometric changes across lifespan remains unclear. Here, leveraging structural magnetic resonance imaging scans from 1,790 healthy individuals aged 8 to 89 years, we investigated age-related global, within- between-network dispersions reveal networks 3D manifolds based on similarity network (MSN), combining multiple features conceptualized “fingerprint” an individual’s brain. Developmental global dispersion unfolded along patterns molecular organization, such acetylcholine receptor.

Short mindfulness-based interventions have gained traction in research due to their positive impact on well-being, cognition, and clinical symptoms across various settings. However, these short-term trainings are viewed as preliminary steps within a more extensive transformative path, presumably leading long-lasting trait changes. Despite this, little is still known about the brain correlates of meditation traits.

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

The human prefrontal cortex (PFC) exhibits markedly protracted developmental plasticity, yet whether reductions in plasticity occur synchronously across cortical layers is unclear. Animal studies have shown that intracortical myelin consolidates neural circuits to close periods of plasticity. Here, we use quantitative imaging collected from youth (ages 10-32 years) at ultra-high field (7T) investigate deep and superficial PFC exhibit different timeframes We find matures along a deep-to-superficial axis the PFC; this maturational timing expressed extent cytoarchitecturally distinct regions frontal hierarchy.
