Our brain is usually well protected from uncontrolled influx of molecules from the periphery thanks to the blood-brain barrier, a physical seal of cells lining the blood vessel walls. The hypothalamus, however, is a notable exception to this rule. Characterized by leaky blood vessels, this region, located at the base of the brain, is exposed to a variety of circulating bioactive molecules. This anatomical feature also determines its function as a rheostat involved in the coordination of energy sensing and feeding behavior.
