of arm entry, as indicated by no significant interaction between the two drugs (p = 0.51), as well as no significant main effect for either rimonabant treatment (p = 0.79) or CP-55,940 treatment (p = 0.25). The data include rats whose cannulae were correctly aimed at the hippocampus (see Figure 1C for cannulae placements). Thus, 0.06 μg was selected as the dose of rimonabant for intracerebral injections in subsequent experiments.
