Neuroimaging and computational neuroscience studies reveal different ways and brain areas implicated in decision making. Read More
Common green apple flavorant farnesene enhances nicotine reward in mouse models. The flavorant is also rewarding on its own. Researchers say with or without nicotine, flavored vapes, especially those containing farnesene, pose potential neurological risks, including addiction. Read More
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.

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
A recent study reveals people are more likely to become more altruistic and charitable as they age. Read More
Neuroimaging study sheds light on what drove the evolutionary development of human creativity. Read More
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
A variant of the FAAH gene increases vulnerability to THC in females and has a larger-scale impact on brain regions responsible for reward processing. Read More
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
Musical anhedonia, a neurological condition where people don't enjoy music, affects 5% of the population. Researchers are exploring if this same condition could also be what impairs social bonding for some people on the autism spectrum. Read More
Exposing subjects to music composed in an unfamiliar scale, researchers test whether reward can be derived solely from newly formed predictions. Read More
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
