Task structures, behavior, and anatomical placements. a Attentional bias task structure. Touching the black target resulted in water reward. Distractors appeared simultaneously with target, but were irrelevant to task contingency. Locations of target and distractor were pseudo random on each trial. b Cue conditioning (self-administration) task structure. First block provided ten water reward (0.07 ml/kg) trials, second block presented 10 i.v. cocaine reward (0.1 mg/kg) trials. c Bias task accuracy. Animal 15-04 is shown in the left bar for each condition, and 19-04 is shown in the right bar. Comparisons are for both animals combined. Accuracy did not differ by distractor condition. d Bias task response times. Cocaine-associated distractors were associated with elongated response times compared with water and non-associated distractors, *p < 0.05. e Summary of electrode placements for each animal. o, OFC; x, ACC; Δ, VST; □, DST. Depths of electrode placements were calculated based on the position of the cranial cylinder in co-registered MR and CT images
