Stage of sleep important for the process of consolidating memories Voyeur chat
The researchers knew about the extensive evidence that in wakefulness, new situations and stimuli can readily prevent new memories from consolidating.
A recent study from this same German research lab has revealed that sleep helps memory formation the most if you know you will need the information later.
That is, it seems that the brain prioritizes its consolidation operations during sleep to favor con-solidation of information that is most important.
Presumably, the brain is using Stage IV to accomplish this differential consolidation process.
In a recent study from a French group, the study focus was on sleep's apparent ability to prioritize memory formation based on prior instructions to remember or for-get items in a learning task.
The study tested 193 volunteers for recall of a variety of memory tasks.
Some subjects were exposed to the learning ma-terial early in the day, when there would be no sleep involved.By the time of the second interfering task some 40 minutes later, much of the initial learning had gelled during sleep, but less so during wakefulness.These authors also performed brain imaging that showed that the nap group had mostly completed a shift in activity from the temporary processing area (in the hippo-campus) to storage areas in the cortex. You might say that sleep enabled the information to be "uploaded from RAM to the hard drive" better than in the constant awake condition.But we now find out from a recent study that the sleep effect on improving memo-ry formation benefits from the relevance of the learned information.Since sleep usually occurs significantly later than the learning and original encoding, this effect must arise from the consolidation process during sleep.For example, during a study session for a school exam, take a nap right away so that it has a better chance to consolidate than if you stayed awake and got exposed to many new interfering situations and stimuli.Tags: Adult Dating, affair dating, sex dating
