According to Japanese media reports, a Japanese research institute has discovered a way to improve memory. Recently, a scientific research team composed of Japan’s RIKEN and others conducted experiments using mice and found that although continuous lack of sleep can lead to memory loss, if a certain amount of brain stimulation is given, memory can be improved without sleep. The results were published in the online edition of the American Journal of Science on May 26.

Japanese study finds way to improve memory

It is reported that this result may overturn the conclusion that sleep is needed to stabilize memory. Riken’s project leader Masayoshi Murayama (Life Sciences) said: “Although it may be used for exam-oriented study in the future, adequate sleep is very important for mental and physical health.”

It is known that falling asleep after studying leads to a better retention of what you have learned. The research team focused on specific nerve conduction functions in parts of the brain related to memory and movement. In an experiment to study the memory of mice, it was found that the above-mentioned conduction function began to activate when the mice fell asleep after learning, making the memory stable.

By modifying genes, researchers have created a group of experimental mice whose conductive functions start to activate as long as their brains are exposed to light. Even if the small cage they sleep in is shaken to prevent them from sleeping, as long as they are given light stimulation, they will still form memories. It is reported that experimental rats have longer-lasting memories than ordinary rats that get enough sleep.

Murayama said that the human brain also has the same nerve conduction function. “It may help develop treatments for patients with memory loss caused by sleep disorders,” he said with anticipation.
