The perirhinal cortex
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. WebbThe prefrontal cortex is presumed to act as a high-level gating or filtering mechanism that enhances goal-directed activations and inhibits irrelevant activations. This filtering mechanism enables executive control at …

However, it has not been clear whether its contribution to performance is … WebbThe perirhinal cortex is juxtallocortex, cortex of a type that is transitional between the neocortex and the archicortex and paleocortex of the hippocampal and entorhinal regions. Unlike the neocortex, area 35 lacks an inner granular layer (layer 4) and this layer is very narrow in area 36.
