Dopamine is an inotropic agent that has vasodilatory effects at low doses. It is a common belief that low-dose dopamine may be helpful in the prevention and treatment of acute renal failure and is ...

A yet unanswered question is whether dopamine agonists and levodopa have different effects on DAT expression, radiotracer affinity and receptor occupancy because the significant difference in striatal ...

In our relentless pursuit of instant gratification within a fast-paced world, the phenomenon of dopamine chasing has emerged as a significant behavioural pattern. This term refers to the ...

The endogenous cannabinoid system has been clearly implicated in each of these debilitating conditions, but a link between maladaptive dopamine dynamics and signaling at cannabinoid receptors is still ...

Recent research from Stanford shows that dopamine and serotonin work in opposition to manage learning and decision-making, with dopamine promoting reward-seeking behavior and serotonin moderating it, ...

That's what's suggested by a new study of how caffeine interacts with the production of the feel-good chemical dopamine. Previous work has established that caffeine interferes with some of the ways ...
