Energy balance includes modulation of dopamine reward signaling — ScienceDaily

Since the discovery of leptin in the 1990s, researchers have wondered, how does leptin, a hormone made by body fat, suppress appetite? Despite tremendous gains in the intervening three decades, many questions still remain. Now, a new study in mice describes novel neurocircuitry between midbrain structures that control feeding behaviors that are under modulatory control by leptin. John Krystal, MD, Editor of Biological Psychiatry, said of the findings, “Omrani and colleagues shed light on how, in non-obese animals, leptin puts the brakes on overeating.” Leptin acts as a critical link…
