This paper answers why can’t you remember being a baby? For over a century, science said you can't remember being a baby because your infant brain was just too "immature" to record anything. researchers assumed your hard drive was basically turned off for the first two years of life. But this wild paper from Yale completely rewrites how we understand human memory.. Researchers literally put awake babies (between 4 and 25 months old) into an fMRI scanner to watch their brains process new visual experiences in real-time. and what they found is mindblowing.. the infant hippocampus isn't turned off at all. it is actively firing, capturing, and encoding episodic memories. they proved that babies with higher hippocampal activity during a new experience formed a highly stable memory trace. the babies are recording the data. the memory of your first birthday, your first steps, the exact layout of the room you slept in.. it was all successfully saved to your brain. so why can't you remember it? the paper concludes that infantile amnesia isn't an "encoding" problem.. it is a "retrieval" problem. your brain recorded everything perfectly. but as you grew, your brain underwent massive developmental shifts, like explosive neurogenesis (the rapid birth of new neurons), which completely restructured your neural networks. the pathways to access those early files got buried or locked away. you didn't fail to make the memories.. you just lost the encryption key to open them. somewhere deep in your hippocampus, the exact first-person memory of being a 1-year-old might still be sitting there. you just can't access the file anymore.. the human brain is terrifyingly beautiful.
