Neurologists Discover Rest Periods Essential for Building Physical Memory
Yomiuri Shimbun: 体で覚えるなら休憩が大事…脳の仕組みを解明
June 15, 2011

During rest periods between training sessions in activities based on “physical memory”, such as playing the piano and riding a bicycle, proteins are produced in the frontal cerebellum and moved to other parts of the brain, scientific researchers have discovered.

“Rest is essential to study,” confirmed the scientific study published in an American journal of psychology on the 15th.

Our memory of information like names is divided between the hippocampus and the cerebral cortex. In the experiment, a board was moved right and left in front of a mouse, and its eye movements were tracked. The mouse which was allowed to rest between training sessions could follow the board perfectly one day later, but the mouse who had no rest had forgotten half the pattern by the next day, which indicated that the breaks were advantageous.

体で覚えるなら休憩が大事…脳の仕組みを解明

ピアノや自転車など体を使って覚える「運動記憶」は、練習の合間の休憩中に小脳の表面で作られるたんぱく質の働きで、小脳の別の部位に移って定着することを、理化学研究所などが突き止めた。

「学習には休憩が大事」という定説を科学的に証明した成果で、米神経科学会誌電子版に15日発表した。

人の名前など知識の記憶は海馬や大脳皮質に刻まれる。運動記憶は小脳で維持されるが、どのように身に着くのかは不明だった。

理研の永雄(ながお)総一チームリーダーらは、左右に動くボードをマウスに見せて、眼球を動かす実験を実施。休憩を挟んで運動したマウスは1日後もほぼ同じ運動ができたが、休憩しないマウスは半分程度忘れており、休憩の有無で運動記憶の定着に差が出た。
