Why don’t we remember specific events during those crucial first few years, when our brains worked overtime to learn so much? A new Yale study finds evidence that we do form memories, but can’t retrieve them.

Why can't we remember when we were babies? Scientists who scanned infants' brains found that they do make memories. The findings suggest these memories may still exist, but are inaccessible to us.

For decades, scientists have been puzzled by a simple question: Why can't you remember being a baby? Even though infants learn rapidly in their early years, most people can't recall anything from before age three.
