Figure 6. A schematic illustration of a medial orbital prefrontal cortical (MOC) network that integrates and regulates incentive-motivational modulation of goal-directed behavior. Solid lines at the bottom of the figure indicate connections within a central motive circuit of the network. See text for details. MOC 13 = medial orbital prefrontal cortex, Brodmann's area 13; VTA = ventral tegmental area; DA = dopamine; NASshell = shell subterritory of the nucleus accumbens, a part of the ventral striatum; VPm = ventromedial subterritory of the ventral pallidum; MD = mediodorsal nucleus of the thalamus.
