Childhood Memories Are Erased By Growth of New Neurons

Elizabeth Prewitt PACEsConnection writer 5/13/1412:00 PM

For most of us, early childhood memories resemble videos posted on Vine: brief, random snippets of various times, places and people. But our difficulty recalling our earliest life moments isn’t a result of diminishing brainpower; quite the contrary, it could be the byproduct of our brains’ processes of self-renewal.

In a study published this week in the journal Science, researchers show that our brains’ continual process of adding new neurons disrupts older memories, making them increasingly foggier or non-existent. Since neural regeneration peaks when we are babies and slows down as we age, this finding might explain why we don’t recall memories from our infancy.
