Abstract: Evidence from psychopharmacological functional neuroimaging begins to elucidate the neurochemical mechanisms of
cognitive control. Here the role of dopamine in two subcomponent processes of cognitive control is discussed: the active maintenance
and the flexible updating of goal-relevant representations. A range of studies have highlighted a role for the prefrontal cortex (pFC) and
its modulation by dopamine in the active maintenance of distractor-resistant goal-relevant representations. This work suggests that
dopamine might modulate top-down signals from the pFC, thereby increasing the activity of posterior cortical regions that process goal-
relevant representations and rendering them distractor-resistant. Conversely, other studies highlight a role for dopamine in the basal
ganglia in cognitive switching, which might reflect a modulation of the selective gating of cortical cognitive and motor programs. We
present a working hypothesis that integrates these two disparate literatures and states that the flexible adaptation of current goal-relevant
