As we grow up, there are little windows of time when we can learn very, very fast, and very, very deeply. Scientists call these moments, critical periods. Real, neurological, biological states when our brain can soak up information like a sponge. Then, these windows of learning close. Locking us in to certain behaviors and skills for the rest of our lives. But … what if we could reopen them? Today, we consider a series of discoveries that are reshaping our understanding of when and how we can learn. And what that could mean for things like PTSD, brain disease, or strokes. And cuddle puddles. It’s a mind-bending discussion. Literally and figuratively.
This is the second episode in an ongoing series hosted by Molly Webster, in conversation with scientists and science-y people, doing work at the furthest edges of what we know. More to come!
