Combined rather than separate pathways for hedonic and sensory aspects of taste in fly larvae ?

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... Plus

    Summary
    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.
