Neural encoding of cocaine-associated distractors: population response. a Mean population response in each region (+ SEM) during attentional bias task, showing the significant encoding by OFC in both animals combined, as well as each separately. Red dots are placed at the end of 200 msec windows (stepped at 20 msec), wherein response differs by paired t test (Bonferroni-corrected p < 0.0011). b Spatial encoding of distractor location in OFC. For each panel, the 2 × 3 array shown in Fig. 1 was divided into three by combining the upper and lower positions that were contralateral, ipsilateral, or central, relative to the hemisphere being recorded from. When the distractor is associated with cocaine, there is a significant contralateral hemifield selectivity. Red dots signify end of 200 msec windows, wherein the response differs by paired t test (Bonferroni-corrected p < 0.0011), thin line is + SEM
