The effects of the dopamine D2/3 agonist quinpirole on incentive value and palatability-based choice in a rodent model of attention-deficit/hyperactivity disorder.

Rationale: Palatability and incentive value influence animal food choice. Dopamine D2/3 receptor signaling may mediate the effects of palatability and incentive value on choice. Dopamine signaling is disrupted in attention-deficit hyperactivity disorder (ADHD).
