Effects of intra-PrL (a) and intra-IL (b) infusions of ATO and of intra-PrL (c) and intra-IL (d) infusions of MPH on premature responses in the 5-CSRTT. Neither compound produced significant effects on premature responding. Data are mean (±SEM) number of premature responses. ##p<0.01, compared with baseline responding (ITI=5.0 s).
