Increased early motivational response to food in adolescent anorexia nervosa revealed by magnetoencephalography

CONCLUSIONS: MEG results speak against an overall reduced motivational response to food in AN. Instead, relative increased early food processing in the visual cortex suggests greater motivated attention. A greater appetitive response to food might be an adaptive mechanism in a state of undernourishment. Yet, this relative increased food processing in AN was no longer present later, arguably reflecting rapid downregulation.PMID:33947486 | DOI:10.1017/S003329172100088X
