From lowering your risk of obesity and cardiovascular disease to improving your concentration and overall daily performance, sleep has been proven to play a critical role in our health.
From lowering your risk of obesity and cardiovascular disease to improving your concentration and overall daily performance, sleep has been proven to play a critical role in our health. In a new study, researchers at University of California San Diego School of Medicine report that sleep may also help people to learn continuously through their lifetime.
Writing in the August 4, 2020 online issue of eLife, researchers used computational models capable of simulating different brain states, such as sleep and awake, to examine how sleep consolidates newly encoded memories and prevents damage to old memories.
“The brain is very busy when we sleep, repeating what we have learned during the day. Sleep helps reorganize memories and presents them in the most efficient way. Our findings suggest that memories are dynamic, not static. In other words, memories, even old memories, are not final. Sleep constantly updates them,” said Maksim Bazhenov, PhD, lead author of the study and professor of medicine at UC San Diego. “We predict that during the sleep cycle, both old and new memories are spontaneously replayed, which prevents forgetting and increases recall performance.”
