美国波士顿大学最新研究发现,大脑内负责定位导航的细胞同时还扮演着“大脑时钟”的角色。研究人员观察老鼠在跑步机上的运动,并研究其大脑网格细胞在掌控时间上所起的作用。他们把老鼠放在跑步机上运动一段时间,然后给它们食物奖励。几次之后,老鼠的大脑会规律性地每隔一秒活跃一下,直到一次运动结束。这表明,大脑网格细胞可整合距离和时间信息,从而形成对各种经历的记忆。这一发现为我们研究大脑如何形成记忆提供了线索。人的网格细胞和人的生理节律各行其道。人的生理节律大约以24小时为一个周期,我们对每天生活的记忆是以空 The latest study by the University of Boston in the United States found that the cells in the brain responsible for positioning navigation also play the role of “brain clock.” Researchers observed the movement of mice on treadmills and investigated the role played by their brain cells in controlling time. They put the rats on the treadmill for a period of time, and then give them food rewards. After a few times, the mouse’s brain is regularly activated every second until it expires. This shows that brain cells can integrate distance and time information to form memories of various experiences. This finding provides clues to our understanding of how the brain forms memories. Human grid cells and human circadian rhythms go its own way. Human circadian rhythm is about 24 hours a cycle, our memory of everyday life is empty
