The sleeping brain behaves as if it’s remembering something « Mind Whimsy
UCLA researchers have discovered that the activity of a brain region known to be involved in learning, memory and Alzheimer’s disease behaves as if it’s remembering something during sleep, even under anesthesia — a finding that counters conventional theories about memory consolidation during sleep.
His team found that the entorhinal cortex showed what is called persistent activity, which is thought to mediate working memory during waking life — for example, when people pay close attention to remember things temporarily, such as recalling a phone number or following directions.
“The big surprise here is that this kind of persistent activity is happening during sleep, pretty much all the time.” Mehta said. “These results are entirely novel and surprising. In fact, this working memory-like persistent activity occurred in the entorhinal cortex even under anesthesia.”
The findings are important, Mehta said, because humans spend one-third of their lives sleeping and a lack of sleep results in adverse effects on health, including learning and memory problems.
Thank you for the added info! very interesting article.
