The Plastic Brain: Can We Stop Neurodegeneration?
The young brain has an extraordinary ability to remodel in response to experience. This ability is called “plasticity,” and it declines with age as our brain circuits mature. But what happens when the brain loses plasticity? Can we boost plasticity at an older age to help the brain self-repair? New research is revealing the mechanisms that underlie plasticity and trying to answer long-standing questions on how to keep our brains in shape.
