What helps the process of consolidating new memories cody linely dating demi
EEG studies find that after a cognitively taxing day, length of REM periods often increase, suggesting that the brain is “resting” from learning during REM.
The increase in REM appears most strikingly after the mind is asked to acquire more declarative memory (remember more facts).
The sleeping person experiences this memory transfer and consolidation at least partly as dreams.
The content of dreams is beyond the scope of Tuck (we put no stock in “dream interpretation”), but it is clear that the person’s activities the previous day play a big part in what the dreams are about.
But even people with injuries and medications that limit REM sleep do not report memory problems and sleep expert Jerome Siegel has been quoted about people with brain injuries who do not go through REM sleep and nevertheless find a way to function normally.
The hippocampus stores unique representations useful for episodic memory while the neocortex allows overlapping representations useful for understanding patterns. The short-term memory is thought to be encoded as patterns of neural activity while long-term memories are structural changes in the brain – the formation of new synapses that are more persistent.For “declarative memory” sleep also seems critical to long-term retention.For simpler conditioning – relating associations between stimuli or a response to a stimulus, the evidence is not as strong, but sleep still seems beneficial for that type of memory.The schematized versions of some of the short-term memories contribute to learning so that even when memory of a specific event is gone, that event still contributed to overall knowledge.Particularly during stage 3 deep sleep, the memories that have been put in the hippocampus (short-term memories formed during the previous day) are redistributed to the neocortex (where they will be long-term memories).
