What Is the Entorhinal Cortex?

The entorhinal cortex is the new or new cerebral cortex, the old or hippocampus, and the intermediary brain that connects the old and new brains. It is derived from the activity of individual neurons in multiple parts of the brain. These neurons are all included Inside the memory structure, technical measurements revealed that some areas of the brain determine the activity of other areas and how the activity spreads. ^[1]

Entorhinal cortex, new brain or new

Entorhinal cortex's "dialogue" between the new brain and the old brain is very important for memory formation during sleep, but researchers have not investigated the role of the entorhinal cortex in this "dialogue", but it seems More like a "game changer".

The entorhinal cortex exhibits so-called "persistent activity", which they believe is to mediate people's memory storage when they are awake. For example, it works when people want to temporarily memorize something, such as a phone number, or when they follow instructions to do something.

A very sensitive monitoring system monitors the activity of neurons in the three target areas of the brain, and also includes the activity of individual neurons, decrypting the precise information of the "talk", even when the neurons are very quiet.

Use self-developed scum mathematical analysis to decrypt this complex information "dialogue". When people sleep, 90% of the neocortex enters slow-wave mode. During this period, its activity fluctuates slowly between active and inactive every second.

The enduring activity of the entorhinal cortex almost always occurs when people are asleep. In fact, this kind of enduring activity similar to working memory can work normally when the person is under anesthesia. This finding is significant because people spend one-third of their lives sleeping, and lack of sleep often has negative health effects, including learning and memory problems.

"Dialogue" occurs between the neocortex and the hippocampus during sleep, and this "talk" can play an important role in memory formation or memory consolidation. In any case, no one can interrupt the "talk" between them. . When people are sleeping, the light in the room is usually dark and quiet. Although there is no input of information in this condition, the brain remains active. They just want to know how this activity happens and which different areas of the brain can "talk" to each other.
