(Telegraph) Memories are made like this – sleeping on them
If you want knowledge to stick then it is best to take a nap after absorbing it, claims new research.
Researchers in Germany showed that the brain is better during sleep than during wakefulness at resisting attempts to scramble or corrupt a recent memory. Their study, published in Nature Neuroscience, provides new insights into the hugely complex process by which we store and retrieve deliberately acquired information – learning, in short.
Earlier research showed that fresh memories, stored temporarily in a region of the brain called the hippocampus, do not gel immediately. It was known that reactivation of those memories soon after learning plays a crucial role in their transfer to more permanent storage in the brain’s “hard drive,” the neocortex.
During wakefulness, however, this period of reactivation renders the memories more fragile. Learning more information at this juncture will likely make it harder to commit the first batch to deep memory.
