Reward function: a promising but (still) underexamined dimension in developmental psychopathology.

The goal of this Special Section is to explore the ways that investigation of reward function can shed light on the development and pathophysiology of psychopathology. Reward function provides a promising starting point for clinical affective neuroscience research because, thanks to the extensive literature on the neural mechanisms of addiction, the functional neuroanatomy, cellular mechanisms, and genetic contributions to reward circuitry have been well delineated (see Russo & Nestler, 2013, for details).
