WebbThe perirhinal cortex may also play a role in novelty detection, but one that differs from the hippocampal formation. Neuronal activity in the perirhinal cortex appears to register novel exposure to objects that is independent of their association with other objects or contexts (Kumaran and Maguire 2007). Moreover, there ... Webb23 feb. 2012 · Thus the term, perirhinal cortex is commonly used, but the term “ectorhinal” is no longer in use for nonhuman primates and rarely used for rodents except in stereotaxic atlases.

"Webb26 nov. 1996 · Cells in the perirhinal cortex, in the lateral entorhinal cortex, and in the subiculum showed selective or coarse tuning to odor stimuli, indicating that the parahippocampal region encodes specific odor representations. In addition, odor representations in each of these areas was observed to persist through the memory delay. " - The perirhinal cortex
