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 ... 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.
