Connecting the dots: social networks in the classroom and white matter connections in the brain / Rosa H. MULDER in Journal of Child Psychology and Psychiatry, 63-12 (December 2022)

Titre : Connecting the dots: social networks in the classroom and white matter connections in the brain Type de document : Texte imprimé et/ou numérique Auteurs : Rosa H. MULDER, Auteur ; Monica LOPEZ-VICENTE, Auteur ; Andrea P. CORTES HIDALGO, Auteur ; Lisa R. STEENKAMP, Auteur ; Berna GUROÄŽLU, Auteur ; Henning TIEMEIER, Auteur ; Ryan L. MUETZEL, Auteur Article en page(s) : p.1622-1630 Langues : Anglais (eng) Mots-clés : Child Humans White Matter/diagnostic imaging Diffusion Tensor Imaging Cross-Sectional Studies Brain/diagnostic imaging Social Networking Bullying behavior Generation R Study brain imaging peer acceptance peer rejection peer victimization white matter microstructure Index. décimale : PER Périodiques Résumé : BACKGROUND: Peer connections in school classrooms play an important role in social-emotional development and mental health. However, research on the association between children's peer relationships and white matter connections in the brain is scarce. We studied associations between peer relationships in the classroom and white matter structural connectivity in a pediatric population-based sample. METHODS: Bullying and victimization, as well as rejection and acceptance, were assessed in classrooms in 634 children at age 7. White matter microstructure (fractional anisotropy (FA), mean diffusivity (MD)) was measured with diffusion tensor imaging at age 10. We examined global metrics of white matter microstructure and used Tract-Based Spatial Statistics (TBSS) for voxel-wise associations. RESULTS: Peer victimization was associated with higher global FA and lower global MD and peer rejection was associated with lower global MD; however, these associations did not remain after multiple testing correction. Voxel-wise TBSS results for peer victimization and rejection were in line with global metrics both in terms of direction and spatial extent of the associations, with associated voxels (p(FWE) <.05) observed throughout the brain (including corpus callosum, corona radiata, sagittal stratum and superior longitudinal fasciculi). CONCLUSIONS: Although based only on cross-sectional data, the findings could indicate accelerated white matter microstructure maturation in certain brain areas of children who are victimized or rejected more often. However, repeated measurements are essential to unravel this complex interplay of peer connections, maturation and brain development over time.

VAN IJZENDOORN, Auteur Article en page(s) : p.491-503 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The parent–child attachment relationship plays an important role in the development of the infant's stress regulation system. However, genetic and epigenetic factors such as FK506 binding protein 51 (FKBP5) genotype and DNA methylation have also been associated with hypothalamus–pituitary–adrenal axis functioning. In the current study, we examined how parent–child dyadic regulation works in concert with genetic and epigenetic aspects of stress regulation. We study the associations of attachment, extreme maternal insensitivity, FKBP5 single nucleotide polymorphism 1360780, and FKBP5 methylation, with cortisol reactivity to the Strange Situation Procedure in 298 14-month-old infants. The results indicate that FKBP5 methylation moderates the associations of FKBP5 genotype and resistant attachment with cortisol reactivity. We conclude that the inclusion of epigenetics in the field of developmental psychopathology may lead to a more precise picture of the interplay between genetic makeup and parenting in shaping stress reactivity.
