‘Talkative’ Brain Regions Create Self-Control Challenges for Teens With Obesity

Obesity risk in teens appears to be associated with stronger connectivity within and between regions of the brain implicated in determining the salience of stimuli. This may have implications for reward processing. Researchers report executive control efforts in the brain decrease when salience and reward-processing regions are engaged in teens with obesity.

Wired for marriage: The neural and genetic links to romantic love

Researchers have identified both genetic and neural mechanisms associated with romantic love and attachment. The maintenance of romantic love is not only associated with subcortical brain regions but also higher-order centers of the brain. The propensity to sustain romantic love appears to also be affected by genetic variability, specifically with genes associated with dopamine, vasopressin, and oxytocin. Read More

Triglycerides control neurons in the reward circuit

Dietary triglycerides directly alter signaling in the reward circuit to regulate behavior. The findings reveal a potential mechanism by which triglyceride-rich diets may lead to adaptions in dopamine signaling that underlie reward deficit and compulsive behaviors. Read More

How the brain processes rewards

Different types of reward have unique effects on the basal ganglia nuclei. Food rewards influence the left hemisphere of the brain, while erotic rewards engage the right lateral globus and left caudate. Financial rewards engage the basal ganglia bilaterally. Read More

Rich rewards: ADHD medication’s effect on the brain

Methylphenidate may boost norepinephrine levels in the prefrontal cortex, which in turn regulates dopaminergic neurons firing in the striatum, when a reward is delivered. The study sheds new light on how medications for ADHD affect the reward system in the brain. Read More
