Figure 5.

Effects of post-training injections of cocaine (2.5 mg/kg) after 0, 1, 2, or a 4 hr delay after the last spatial training trial. The moderate low dose of cocaine facilitated spatial memory performance on the Morris water maze only when administered within 2 hr of spatial memory training (a). Cocaine did not influence swim velocity (cm/sec) between any of the groups across the different time delays (b). Data is presented as a percent of VEH-treated controls. *Indicates p<0.05 when compared to controls.
