Figure 2 is a schematic diagram depicting the theorized longitudinal developmental trajectories for selected white-matter tissue tracts, functional responses and aspects of dopaminergic development hypothesized to relate to initial responsiveness to reward attainment (RDoC) and to the development of childhood and adolescent addictive and impulsive disorders. Trajectories are based on data reported in (Casey, 2014; Galvan, et al., 2006; Giedd, 2004; Gogtay, et al., 2004; Lebel & Beaulieu, 2011; Lebel, et al., 2008; Raznahan, et al., 2014; Wahlstrom, et al., 2010b).
DLPFC = dorsolateral prefrontal cortex; OFC = orbitofrontal cortex; PFC = prefrontal cortex
