Quizplus · Accepted Answer

Studies have suggested that dopamine plays a role in mediating the effects of leptin in the brain. Leptin acts on the hypothalamus to decrease appetite and increase energy expenditure. Dopamine is involved in reward, motivation, and food intake, and several studies have shown that dopamine neurons in the hypothalamus respond to leptin. Additionally, leptin has been shown to increase dopamine release in certain brain regions, suggesting that dopamine may be a key mediator of leptin's effects on feeding behavior.
