近日,科学家发现了一种可以将记忆像普通开关一样随意开启和关闭的方法。科学家们复制出与记忆相关的神经信号发放,设计出一个电子信息系统,能够在大鼠体内模仿与长期记忆相关的脑部功能,甚至是当大鼠服用导致失忆的药物后该系统也同样有效。“开关打开,然后大鼠就恢复记忆;开关关闭,大鼠就丢失记忆。”来自南加州大学维特比工学院(USC Viterbi School of Engineering)工程系生物医药工程的西奥多·柏格(Theodore Berger)教授如是 Recently, scientists have discovered a way to turn memories on and off as easily as ordinary switches. Scientists replicate memory-related neuronal signaling, devising an electronic information system that mimics long-term memory-related brain functions in rats, even when rats take drugs that cause memory loss . The switch is turned on and the rat regains memory and the switch is turned off and the rat loses memory.
