Entorhinal cortex
From Psy3242
Overview
One of the first areas to be affected by Alheimer's Disease, the entorhinal cortex plays a crucial role in memory, specifically memory consolidation (the process in which short-term memories are organized and stored as a piece of long-term memory), and memory optimization during sleep. It forms the main input to the hippocampus (commonly called the memory center).
