Study provides surprising new clue to the roots of hunger
Date:2/7/2014

gry after a period of no food ate very little when these upstream neurons were turned off.

"This has led us to the discovery of a novel, previously unknown means of activating AgRP neurons and producing hunger," explains Lowell. "Surprisingly, these hunger-inducing neurons were found in a region of the brain which has long been thought to have the opposite effect causing satiety. This unexpected discovery, made possible only through the use of the new wiring diagram-elucidating technologies, highlights the importance of following the labeled neuronal lines of information flow. We are getting closer and closer to completing our wiring diagram, and the nearer we come to understanding how it all works, the better our chances of being able to treat obesity and eating disorders, the consequences of abnormal hunger."
