Study further expands understanding of leptin's role in brain neurocircuitry

...sis through its effects on the central nervous system. Over the years, investigators have pinpointed a region of the brain's hypothalamus known as the arcuate nucleus (ARC) as one key area where leptin exerts its influence, and within the ARC, they have identified two types of leptin-responsive neurons, the ...

Serotonin the Answer for Anti-Obesity Treatment

... fenfluramine affected the brain's molecular pathways to reduce appetite. In 2002, they examined the region of the brain's hypothalamus containing the arcuate nucleus, or ARC. In the ARC, drug-induced serotonin activates brain cells called pro-opiomelanocortin neurons, or POMC, which in turn release a hormon...
