Stress-induced activation of the HPA axis predicts connectivity between subgenual cingulate and salience network during rest in adolescents / Moriah E. THOMASON in Journal of Child Psychology and Psychiatry, 52-10 (October 2011)
[article]
Titre : Stress-induced activation of the HPA axis predicts connectivity between subgenual cingulate and salience network during rest in adolescents Type de document : Texte imprimé et/ou numérique Auteurs : Moriah E. THOMASON, Auteur ; J. Paul HAMILTON, Auteur ; Ian H. GOTLIB, Auteur Année de publication : 2011 Article en page(s) : p.1026-1034 Langues : Anglais (eng) Mots-clés : Resting-state adolescents HPA axis stress subgenual cingulate fMRI salience network connectivity Index. décimale : PER Périodiques Résumé : Background: Responses to stress vary greatly in young adolescents, and little is known about neural correlates of the stress response in youth. The purpose of this study was to examine whether variability in cortisol responsivity following a social stress test in young adolescents is associated with altered neural functional connectivity (FC) of the salience network (SN) measured during resting-state functional magnetic resonance imaging (rs-fMRI).
Methods: Forty-nine typically developing young adolescents participated in a social stress test during which they contributed salivary cortisol samples. Following this, they underwent rs-fMRI scanning. We examined the association of FC of the SN [composed of anterior cingulate cortex and bilateral anterior insula regions] with cortisol responsivity.
Results: Greater cortisol responsivity was significantly positively correlated with higher FC between subgenual anterior cingulate cortex (Cg25) and the SN, controlling for participant age. There were no regions of the brain that showed an inverse relation.
Conclusions: Brain systems that have been implicated in autonomic arousal and that influence subjective feeling states show altered FC associated with stress responsivity in early life.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2011.02422.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=142
