Breastfeeding, brain activation to own infant cry, and maternal sensitivity / Pilyoung KIM in Journal of Child Psychology and Psychiatry, 52-8 (August 2011)
[article]
Titre : Breastfeeding, brain activation to own infant cry, and maternal sensitivity Type de document : Texte imprimé et/ou numérique Auteurs : Pilyoung KIM, Auteur ; Ruth FELDMAN, Auteur ; Linda C. MAYES, Auteur ; Virginia EICHER, Auteur ; Nancy THOMPSON, Auteur ; James F. LECKMAN, Auteur ; James E. SWAIN, Auteur Année de publication : 2011 Article en page(s) : p.907-915 Langues : Anglais (eng) Mots-clés : Breastfeeding infancy maternal sensitivity mother–infant interaction neuroimaging Index. décimale : PER Périodiques Résumé : Background: Research points to the importance of breastfeeding for promoting close mother–infant contact and social-emotional development. Recent functional magnetic resonance imaging (fMRI) studies have identified brain regions related to maternal behaviors. However, little research has addressed the neurobiological mechanisms underlying the relationship between breastfeeding and maternal behavior in human mothers. We investigated the associations between breastfeeding, maternal brain response to own infant stimuli, and maternal sensitivity in the early postpartum.
Methods: Seventeen biological mothers of healthy infants participated in two matched groups according to feeding method – exclusive breastfeeding and exclusive formula-feeding at 2–4 weeks postpartum. fMRI scanning was conducted in the first postpartum month to examine maternal brain activation in response to her own baby’s cry versus control baby-cry. Dyadic interactions between mothers and infants at 3–4 months postpartum were videotaped in the home and blindly coded for maternal sensitivity.
Results: In the first postpartum month, breastfeeding mothers showed greater activations in the superior frontal gyrus, insula, precuneus, striatum, and amygdala while listening to their own baby-cry as compared to formula-feeding mothers. For both breastfeeding and formula-feeding mothers, greater activations in the right superior frontal gyrus and amygdala were associated with higher maternal sensitivity at 3–4 months postpartum.
Conclusions: Results suggest links between breastfeeding and greater response to infant cues in brain regions implicated in maternal–infant bonding and empathy during the early postpartum. Such brain activations may facilitate greater maternal sensitivity as infants enter their social world.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2011.02406.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=132

Titre : Stress and the healthy adolescent brain: Evidence for the neural embedding of life events Type de document : Texte imprimé et/ou numérique Auteurs : Barbara L. GANZEL, Auteur ; Pilyoung KIM, Auteur ; Heather GILMORE, Auteur ; Nim TOTTENHAM, Auteur ; Elise TEMPLE, Auteur Article en page(s) : p.879-889 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Little is known about the long-term neural consequences of adverse life events for healthy adolescents, and this is particularly the case for events that occur after a putative stress-sensitive period in early childhood. In this functional magnetic resonance imaging study of healthy adolescents, we found that prior exposure to severe adverse life events was associated with current anxiety and with increased amygdala reactivity to standardized emotional stimuli (viewing of fearful faces relative to calm ones). Conjunction analyses identified multiple regions, including the amygdala, insula, and prefrontal cortex, in which reactivity to emotional faces covaried with life events as well as with current anxiety. Our morphometric analyses suggest systemic alterations in structural brain development with an association between anxiety symptoms and global gray matter volume. No life events were reported for the period before 4 years of age, suggesting that these results were not driven by exposure to stress during an early sensitive period in development. Overall, these data suggest systemic effects of traumatic events on the dynamically developing brain that are present even in a nonclinical sample of adolescents.
