Oxytocin (OXT) modulates amygdala connectivity and attenuates responses to psychosocial stress, but its effect appears to be moderated by ELS. Here we first investigate the effect of ELS on amygdala-prefrontal rs-FC, and examine whether ELS-associated changes of rs-FC in this neural circuit predict its response to psychosocial stress. Secondly, we explore the joint effect of OXT and ELS on the amygdala-prefrontal circuit. Eighteen healthy young males participated in a resting-state fMRI study of OXT effects using a double-blind, randomized, placebo-controlled, within-subject crossover design. We measured the rs-FC to bilateral amygdalae and subsequently assessed changes of state anxiety and prefrontal responses to psychosocial stress. Multiple linear regressions showed that ELS, specifically emotional abuse, predicted reduced rs-FC between the right amygdala and pregenual anterior cingulate cortex (pgACC), which in turn predicted elevated state anxiety after psychosocial stress. In subjects with lower ELS scores, stronger pgACC-amygdala rs-FC predicted stronger pgACC deactivation during the psychosocial stress task, and this rest-task interaction was attenuated by OXT. In subjects with higher ELS scores however, the rest-task interaction was altered and OXT showed no significant effect. These findings highlight that ELS reduces pgACC-amygdala rs-FC and alters how rs-FC of this circuit predicts its stress responsiveness. Such changes in pgACC-amygdala functional dynamics may underlie the altered sensitivity to the effects of OXT after ELS.</dcterms:abstract> <bibo:uri rdf:resource="https://kops.uni-konstanz.de/handle/123456789/38300"/> <dc:creator>Otte, Christian</dc:creator> <dc:contributor>Herrera-Melendez, Ana Lucia</dc:contributor> <dc:language>eng</dc:language> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/43"/> <dc:rights>terms-of-use</dc:rights> <dc:creator>Aust, Sabine</dc:creator> <dc:creator>Bajbouj, Malek</dc:creator> <dc:creator>Feeser, Melanie</dc:creator> <dc:creator>Herrera-Melendez, Ana Lucia</dc:creator> <dc:contributor>Pestke, Karin</dc:contributor> <dc:contributor>Aust, Sabine</dc:contributor> <dc:contributor>Grimm, Simone</dc:contributor> <dc:contributor>Pruessner, Jens C.</dc:contributor> <dcterms:title>Early life stress modulates amygdala-prefrontal functional connectivity : Implications for oxytocin effects</dcterms:title> <dc:contributor>Feeser, Melanie</dc:contributor> <dc:creator>Grimm, Simone</dc:creator> <dc:contributor>Böker, Heinz</dc:contributor> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2017-04-04T11:01:44Z</dc:date> </rdf:Description> </rdf:RDF>
