UCLA Health researchers have identified a process that memories while reducing metabolic costs, even during sleep. This efficient memory is found in a brain region essential for learning and memory, which is also where Alzheimer’s disease originates.
The discovery is published in the journal Nature Communications.
Does this sound familiar: You go to the kitchen to fetch something, but when you get there, you forget what you wanted. This is your working memory failing. Working memory is defined as remembering some information for a short period while you go about doing other things. We use working memory virtually all the time. Alzheimer’s and dementia patients have working memory deficits and it also shows up in mild cognitive impairment (MCI). Hence, considerable effort has been devoted to understanding the mechanisms by which the vast networks of neurons in the brain create working memory.
