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.

Researchers used fMRI to study effort-based decision-making and found two distinct regions of the ventral striatum associated with different phases of physical effort. The findings provide new insights into motivation, depression, schizophrenia, and PTSD.
Research suggests that higher reward-related ventral striatum activity may protect against depressive symptoms associated with poor sleep quality. The study found that students with higher VS activity were less likely to report symptoms of depression when experiencing poor sleep quality.

Researchers used advanced brain imaging techniques to study how beer flavor affects brain activity in beer drinkers. The study found that the right ventral striatum, a deep structure linked to motivated behavior and reward, showed increased activity in response to beer taste.
Cocaine users exhibit hyperactivation in the ventral striatum, a region critical for reward processing, and display anomalous activation profiles in the prefrontal cortex. Structural differences, including hypertrophy of key brain regions, contribute to the development of compulsive behaviors and difficulties in controlling impulses.

A new study suggests that brain activity can predict how likely young adults are to develop problem drinking or engage in risky sexual behavior. The research found that imbalance in the function of typically complementary brain areas, such as the ventral striatum and amygdala, is associated with increased risk.

A study from Johns Hopkins Medicine found that performance is influenced by a person's aversion to loss, with those having high loss aversion doing better when faced with large prospective losses but choking under pressure of large gains. Brain imaging revealed the ventral striatum as the key brain area involved in this process.
Researchers at MIT have developed a technique that allows them to track neural communication in the brain over time, offering a new window on brain function. The technique uses magnetic resonance imaging (MRI) along with a specialized molecular sensor to monitor dopamine levels in specific regions of the brain.
