title: Combined rather than separate pathways for hedonic and sensory aspects of taste in fly larvae?
abstract: In mammals, the hedonic aspects (good versus bad) and sensory aspects (i.e., the molecular quality) of taste are associated with different brain regions. Anatomical data argue against such a separation in the primary taste center of Drosophila larvae. Is only one aspect of taste represented or do both co-exist at the same location? I present evidence for a hedonic representation in the larval taste center and review anatomical and behavioral data which support the co-existence of a sensory representation of taste with a hedonic representation.
