Figure 3. — Effect of saline (sal) or muscimol (62.5 and 125 ng/side) infused into the cingulate cortex before the sample phase on novel object recognition after a retention delay of 24 h. N = 11 rats in total. (A) Timeline of experiment 3 to illustrate the 24-h retention delay between the sample and the choice phase, the timing of the infusions 10 min before the sample phase and the repeated (×3) testing in the within-subjects design. (B) Effect of muscimol on the first minute of exploration time (sec, mean ± SEM) of a novel (Nov) and a familiar (Fam) object during the choice phase. (*) P < 0.05, (**) P < 0.001, significant difference when compared with the familiar object. (C) Choice performance presented as the discrimination ratio during the first minute of exploration (mean ± SEM); stippled line indicates chance. (#) P < 0.05, (##) P < 0.001, significantly different from chance.
