The entorhinal cortex is a region of the brain located in the medial temporal lobe. It plays a crucial role in memory and navigation, serving as a hub for information flow between the hippocampus and other areas of the brain. This area is involved in processing spatial memory and is essential for recognizing familiar environments. Additionally, the entorhinal cortex contains specialized cells known as grid cells, which help in mapping out spatial locations. These cells enable the brain to understand and navigate through space, contributing to our ability to remember places and routes.
