A, B, Target-related (A) and lure-related (B) neural activity as a function of inferred PFC dopamine status (event-related activity on correct trials within 2- and 3-back WM blocks; note that 0-back blocks do not, by necessity, contain lure trials). C, Two-back lure performance versus the magnitude of correct lure-trial activity in right (R) MFG (mean signal within the ROI). D, COMT enzyme versus the magnitude of correct lure-trial activity in right MFG (mean signal). e, Estradiol.
