Talkative' brain regions create self-control challenges for teens with obesity

Weight‐Related Differences in Salience, Default Mode, and Executive Function Network Connectivity in Adolescents, Obesity (2020).
Lower connectivity between salience network and executive function network regions may suggest that executive-control efforts are going "off-line" when salience and reward-processing regions are engaged in adolescents who have obesity.
Obesity appears to be related to stronger connectivity within and between regions implicated in determining the salience of stimuli, which may have implications for reward processing.
These regions, however, are less connected to those involved in memory and executive functioning—such as decision-making, attention and behavioral control—that could make teens more sensitive to rewards like junk foods, according to a new University of Michigan study.
