The neural basis of nonvisual object recognition memory in the rat.
Bottom Line: The hippocampal findings prompted Experiment 2.Across two replications, no evidence was found that hippocampal lesions impair nonvisual object recognition.These findings reveal a network of linked c-fos activations that share superficial features with those associated with visual recognition but differ in the fine details; for example, in the locus of the perirhinal cortex activation.

Mentions: While the initial (Session 1) object recognition scores (D1, D2) of the two groups appeared closely matched, they looked very different by Session 13 (Figure 3 left). This pattern was expected as in Session 13 the Group Novel rats explored one novel and one familiar object per trial. In contrast, Group Familiar rats were given two familiar objects per trial (as they had been explored on all preceding sessions), resulting in much lower D1 and D2 scores. This pattern was confirmed by more formal analyses.
