Why Is Learning a New Language Harder After Childhood? Australian Broadcasting Corporation - Brisbane Writers Festival What is brain plasticity? It’s a term that explains how brain functions aren't rigid and set in stone at an early age, but rather are changeable and adaptable. Put simply, an old dog CAN learn new tricks...but they need to apply themselves. It's "use it, or lose it."In his return to the Brisbane Writers Festival, Norman Doidge gives an update on some of the latest findings relating to brain plasticity. He explains how understanding that the brain can change itself has huge potential for new treatments for neurological problems, and can also inform what we know about how the human brain grows, learns and adapts.Doidge tells the remarkable story of how, in his last visit to Brisbane in 2008, he met a woman Jane Gapp whose daughter had the incurable condition Locked-In Syndrome. Reading Doidge's book compelled Gapp to persevere in her attempts to help her daughter recover, and she has since pulled her out of her "Locked-In" state.
