Is it possible to enhance and rewire the adult brain?

From Guardian Science Weekly podcast: Nicola Davis asks: can we increase the window of brain plasticity in the later stages of life? And what do we know about the implications of doing so? In early development, the brain is hard at work making new connections between neurons, based on the new experiences we’re having. But the science around brain plasticity – ie the mind’s ability to learn, change and reorganise itself – is advancing. Research looking at people with severe neurological or physical damage tells us a lot about the possibility of enhancing the ability for our brain to rewire.
