Graded Encoding of Food Odor Value in the Drosophila Brain

, 2013
Odors are highly evocative, yet how and where in the brain odors derive meaning remains unknown. Our analysis of the Drosophila brain extends the role of a small number of hunger-sensing neurons to include food-odor value representation.
