A computational framework has been created to understand how the brain's striatum region influences everyday decisions and impaired decision-making in individuals with psychiatric disorders. The study suggests that modulating striosomal activity could be a new approach to addressing psychiatric abnormalities.
Researchers from Kyoto University and Cambridge University developed a fluorescent dopamine sensor to monitor dopamine signals in primate brains. The study found that dopamine signals varied depending on the location in the striatum, with distinct patterns observed in the anterior putamen and caudate head.
People with musical anhedonia still derive pleasure from groovy tunes, and the urge to move appears to drive their experience of pleasure. Research found no differences in either pleasure or urge to move in anhedonics compared to controls, suggesting that the urge to move may itself generate pleasure.
Research reveals that individuals with OCD exhibit lower-than-normal learning rates when rewards are less than expected, while those with problem gambling display boosted learning from high rewards and blunted learning from low rewards. This study highlights the benefits of using neurocomputational approaches to understand psychiatric ...

USC scientists have created a comprehensive map of the dorsal striatum, a part of the brain responsible for motor learning and coordination. The study identifies 29 distinct areas and hubs that coordinate complex limb movements, potentially leading to new treatments for autism and Huntington's disease.
Researchers found that the brain prioritizes calorie intake over taste quality when it comes to sugary foods. The study suggests that the brain has two separate pathways for processing sweetness and energy signals, with calorie-rich foods dominating our desire for sweets.
