新华社华盛顿电如果有一天你发现脑海中那些有趣、幸福或恐怖事,都是别人编造植入,不要惊讶,这并非天方夜谭。美国一研究团队25日宣布,他们已成功给小鼠的大脑植入虚假记忆,从实验上证实了人为改造记忆的可能性。植入记忆的难点有两个:首先,准确地找到只和某一个特定记忆有关的脑细胞;其次,在时间和空间上精确地激活这些细胞,从而重现这段记忆。1年前,美国麻省理工学院脑与认知科学系利根川进教授所在实验室研究人员在《自然》杂志上发表文章,介绍了他们如何通过光遗传学手段标记并激活与一个特定记忆相关的脑细胞,从而人为激活某个记忆
Xinhua News Agency, Washington, DC. If one day you find that those interesting, happy or horrible things in your mind are implanted by others, do not be surprised. This is not a fantasy. A team of researchers from the United States announced on the 25th that they have succeeded in implanting fake memories into mice ’s brains and experimentally confirmed the possibility of artificial modification of memories. There are two difficulties in implanting memory: first, finding exactly the brain cells that are associated with only one particular memory; and second, precisely reproducing these cells temporally and spatially. A year ago, researchers at the University of Massachusetts Institute of Technology’s Brain and Cognitive Sciences, Professor Tonegigen Kawaguchi, published an article in Nature that describes how they can be used to mark and activate photorefractive-related Brain cells, which artificially activate a memory
