Figure 2.

Effect of saline (sal) or SKF81297 (0.4 and 0.8 mg/kg) injected before the sample phase on novel object recognition after a retention delay of 24 h. (A) Timeline of experiment 2 to illustrate the 24 h retention delay between the sample and the choice phase and the timing of injections 15 min before the sample phase. (B) Effect of SKF81297 on the first min of exploration of a novel (Nov) and a familiar (Fam) object during the choice phase.*p<0.05, significant difference compared to familiar object. (C) Choice performance presented as discrimination ratio; stippled line indicates chance. ^#p<0.05, significantly different from chance. Data are shown as a mean±S.E.M (n=11-12 rats per group).
