Significant advancements have been made in the past century regarding the neuronal
control of feeding behavior and energy expenditure. The effects and mechanisms of action
of various peripheral metabolic signals on the brain have become clearer. Molecular and
genetic tools for visualizing and manipulating individual components of brain homeostatic
systems in combination with neuroanatomical, electrophysiological, behavioral, and
pharmacological techniques have begun to elucidate the molecular and neuronal …
