eLife: Can sleep protect older people's memories?

6, 2020 /--- -- In a new study, researchers at the University of California, San Diego School of Medicine found that sleep can help people learn for life.
an article published in the journal elife on August 4, 2020, the authors used computational models that simulated different brain states, such as sleep and wakeliness, to examine how sleep consolidates newly encoded memories and prevents damage to old ones.
is actually very busy during sleep because it needs to repeat what you learn during the day.
helps to reorgotate memories and present them in the most effective way.
our findings suggest that memories are dynamic, not static.
we predict that old and new memories will be spontaneously replayed during the sleep cycle, which prevents forgetting and improves memory.
, author of the article ," (Photo source: www.pixabay.com), says memory replay during sleep protects against forgetting by allowing the same number of neurons to store multiple interfering memories.
"We learn a lot of new things every day, and new memories compete with old ones.
so to hold all the memories, we need enough sleep.
" "For example, our muscles also have a certain memory, after learning to play tennis to continue to learn to play golf, our muscles need to master different types of force.
ensures that learning golf doesn't erase the tennis posture we master.
, sleep makes it possible for different memories to coexist in the brain.
authors argue that the value of restoring sleep may be lacking in artificial intelligence systems.
these AI systems lack the ability to continue learning and forget old knowledge as they learn new information.
may need to add sleep-like states to computers and robotic systems to prevent them from forgetting after new learning and to enable them to learn continuously, " says Bazhenov.
" Bazhenov said the results could lead to the development of new stimulation techniques during sleep to improve memory and learning.
may be particularly important for older people or people with learning disabilities.
