How to improve memory
A recent study by German scientists found that sleep helps transform short-term memory into long-term memory.
Previous studies have shown that short-term memory is stored in a part of the brain called the hippocampus, and long-term memory is stored in a part called the neocortex, similar to the functions of computer memory and hard drives. Recalling what you just remembered in a short period of time plays an important role in turning short-term memory into long-term memory.
When awake, the process of repeating memory contents is easily disturbed and it is difficult to form long-term memories.
Agence France-Presse reported on the 24th that a research report published by the researchers of the University of Lubeck in the latest issue of the "Natural Journal of Neurology" showed that people are not easily disturbed when they "recall" the contents of memory during sleep.
The researchers gave 24 volunteers some cards containing animals and daily necessities. While the volunteers remembered the contents of the card, the researchers cast a little unpleasant smell.
Forty minutes later, the researchers asked 12 volunteers to start memorizing other cards with slightly different patterns. Before the memory started, they cast the previous scent again to help volunteers recall the first batch of cards.
The other half of the volunteers slept for a while before beginning to remember the second batch of cards. In the meantime, the researchers cast the same bad smell.
The experiment found that volunteers who have been sober can recall 60% of the first batch of card content on average, and the content remembered by volunteers who took a nap for an average of 85%.
Susan Deckerman, lead author of the research report, said: "According to brain imaging data, we believe that within the first few minutes of sleep, memory contents begin to transfer from the hippocampus to the neocortex. It produces this unexpected result.
Deckerman said that the actual working process of the brain is not exactly the same as that of the computer. "Human memory is completely dynamic. Memory is not 'archived' in the neocortex in a static manner, but constantly changing under various influencing factors."
Recalling is not simply "reading" the contents of the memory, but "a process of reconstruction, in which the memory may change and make mistakes."
