You Don’t Remember Being a Baby, but Your Brain Was 
Making Memories
研究发现,我们婴儿时期的记忆可能并未消失
词量:340 词
Article
Main idea
Most adults cannot recall events before the age of four, a gap called 
infantile amnesia. Two main explanations have been proposed. The first 
blames the immature hippocampus, a deep brain region essential for 
memory. In this view, babies are like adult patients who lose the ability 
to store memories after damage to this area. The second suggests that 
memories are stored early but become inaccessible later, much like 
forgotten files on a computer.
段落大意:指出成人普遍无法回
忆四岁前的经历,并引入“婴儿
期遗忘”这一概念。
论证方法:通过“普遍现象”进
行事实论证,并给出两种主流解
释作对比论证。
文章逻辑:开篇提出核心议题,
为下文展开实验研究做铺垫。
Recent work on mice supports the second idea. By stimulating 
special neurons in the hippocampus, scientists could retrieve memories 
that had seemed lost. But can human infants form memories in the first 
place?
段落大意:介绍小鼠实验支持
“记忆被储存但无法读取”的第
二解释。
论证方法:以“小鼠实验”为例
证,通过因果论证说明刺激神经
元可恢复记忆。
文章逻辑:承接首段两种解释,
用动物实验为下文人类研究提供
理论支持。
For ten years, our lab has faced the challenge of scanning awake 
babies with functional magnetic resonance imaging (fMRI). Unlike 
sleeping infants, awake ones move, cry and ignore instructions. After 
more than 400 sessions, we developed games, songs and tiny mirrors to 
keep them still and happy.
段落大意:描述实验室十年来如
何克服扫描清醒婴儿的技术难
题。
论证方法:通过具体数字
(400+ sessions )与对比论证
(清醒 vs 熟睡婴儿)突出困难
与解决策略。
文章逻辑:从理论过渡到实践,
展现研究可行性,为实验结果的
可信度作铺垫。
In our latest study, led by Tristan Yates, we showed one-year-olds 
pictures of faces, objects and scenes while recording hippocampal activity. 
Minutes later, each familiar picture was paired with a new one of the 
same kind. Babies looked longer at the photographs they had seen before, 
a sign of memory. Looking back at the brain data, we found that the 
hippocampus was more active during the first viewing of pictures that 
were later remembered. The clearest effects appeared after 12 months of 
age and in a subregion crucial for adult episodic memory.
段落大意:报告最新实验过程与
结果——1 岁婴儿的海马体可形
成记忆。
论证方法:实验流程描述(展示
图片→注视时间测量→脑区活动
对比)形成因果链;用数据对比
(12 个月后效应更显著)强化
结论。
文章逻辑:提供核心实证,直接
回答“婴儿能否形成记忆”的疑
问。
These findings indicate that the infant brain is already laying down 
memories, yet most of them remain locked away for life. Why they stay 
hidden, and whether we could ever unlock them, remains an open question.

大多数成年人无法回忆起四岁以前的经历,这段空白被称为“婴儿期遗忘”。对此,学界提出
了两种主要解释。第一种归咎于尚未成熟的海马体——大脑深处一个对记忆至关重要的区域。按此
观点,婴儿与那些因该区域受损而丧失记忆储存能力的成年病人无异。第二种则认为,记忆其实早
在婴儿期就已形成,只是后来变得无法读取,就像电脑里被遗忘的文件。
近期对老鼠的研究支持了第二种观点。通过刺激海马体内的特定神经元,科学家成功唤回了那
些看似已消失的记忆。然而,人类婴儿究竟能不能形成记忆呢?
十年来,我们实验室一直致力于用功能性磁共振成像(fMRI)扫描清醒的婴儿。与熟睡的婴儿
不同,醒着的他们常常扭动、哭闹,不听指令。经过四百多次尝试,我们设计出游戏、儿歌和小镜
子,让他们既安静又开心。
在特里斯坦·耶茨主持的这项最新研究中,我们给一岁左右的婴儿观看人脸、物品和场景的图
片,同时记录海马体的活动。几分钟后,每张熟悉的图片都与同类的新图配对出现。婴儿对自己见
过的照片注视时间更长,这是记忆存在的标志。回溯脑数据,我们发现:后来能被记住的图片,在
首次呈现时海马体反应更强。这种效应在12 个月以上的婴儿中最为明显,且集中在成年情景记忆
所依赖的海马体亚区。
这些发现表明,婴儿大脑已在“存档”记忆,但这些记忆大多终生封存。它们为何深藏不露?
我们能否有朝一日解锁它们?仍是未解之谜。破解这一谜团或许能为我们理解语言习得、发育障碍
乃至老年记忆衰退带来新的曙光。
