Where this comes from

Abstract

The brain melanocortin system is a primary gateway through which energy balance is controlled. Diano and colleagues report a novel cellular mechanism mediated via reactive oxygen species (ROS) that regulates the activity of these melanocortin neurons in response to energy status, thereby modulating appetitive behavior (Diano et al., 2011).
