Coordinated activity between the striatum and hippocampus enriches teens' ability to learn and form new memories, a new study reports.
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.
Researchers report the striatum acts as a sensory hub which integrates various types of sensory information.
Researchers discover that when people choose between two or more positive outcomes, they experience paradoxical feelings of pleasure and anxiety.
Social status can determine differences between sizes of different brain regions in primates, a new study reports.
Findings could have major implications for future studies into motivation, addiction and decision making, researchers report.
Choice bias is a byproduct of learning from reward, a new study reports.
According to a new study, a genetic variation in the FOXP2 gene is associated with the ability for adults to learn new languages.
Researchers report chronic stress can influence how we make decisions. In a new study, mice who were affected by chronic stress were more likely to make more risky decisions with higher payoff options than those who were less stressed.
Researchers identify an aspect of brain activity that helps to predict the effectiveness of a reward-based strategy as motivation to quit smoking.
A new study reports those with alcohol addiction who also smoke may be at an increased risk of neural damage. The study revealed higher levels of oxidative stress in the hippocampus, and a a decrease in neurotrophic factor in the striatum and frontal cortex in rats exposed to both alcohol and tobacco.
Researchers improve motor function and reduce brain shrinkage in animal models of HD by adjusting the levels of a signaling protein.
