riadik2000 [5.3K]
Sleep reactivates recent experiences stored in the hippocampus and shifts them for permanent storage in the cortex. The hioppocampus is the portion of the brain that is responsible of storing of the long-term memory which would include the experiences and the pas t knowledge. It is located in the medial temporal lobe of the brain. As one sleeps, the brain would sort of replay everything that happened that day. At this time, the hippocampus and the neocortex would communicate with each other to make and store those memories. From researches, it was said that the activity of the hippocampus would increase when an individual is in a slow-wave sleep.
