The perirhinal cortex
WebbThe human perirhinal cortex and semantic memory. Studies in macaque monkeys indicate that the perirhinal cortex in the temporal lobe participates in object memory. This … Webb10 apr. 2024 · Here, we identified neural signatures of a predictive map of task behavior in perirhinal cortex (Prh). Mice learned to perform a tactile working memory task by classifying sequential whisker stimuli over multiple training stages. Chemogenetic inactivation demonstrated that Prh is involved in task learning.
