Succimer treatment of the High-Pb rats was either ineffective or only partially effective in alleviating the impairments in learning, inhibitory control, and early-session attentional function. Percent premature responses in attention task 1 as a function of (A) the duration of the pre-cue delay (averaged across the 20 sessions) and (B) stage of testing (averaged across the pre-cue delay). (C) Percent premature responses in the sustained attention task as a function of the duration of the delay between trial onset and cue presentation. (D) Percent omission errors committed during the first block of trials in each session (trials 1–66) in the sustained attention task as a function of cue duration (slopes for High-Pb vs. control; p = 0.009). Data points are means ± SEs.
