Protein synthesis in the cortex is required for long-term object recognition memory. (A) Schematic representation of the behavioral protocol used. 90 min (STM), 24 h (LTM). (B) Recognition indexes on object recognition memory test. Two-way ANOVA for short-term memory (STM) groups showed no differences. Anisomycin (ANI), vehicle (VEH), perirhinal cortex (PRH), insular cortex (IC), hippocampus (HIP), basolateral amygdala (BLA). Two-way ANOVA for LTM showed significant differences between groups; Fisher’s post hoc test revealed that the groups infused with ANI into PRH or IC were different from all the vehicle control groups. ** P < 0.01.
