Brain plasticity is the brain’s ability to adapt to change across the lifespan and to rewire itself after damage. With every new experience, the brain changes in some way. As we experience an event or learn a new skill, new connections are formed between neurons, and connections that aren’t needed anymore are eliminated.
This reorganization of the pathways in our brain takes place at an astounding rate when we are young and rapidly acquiring new information, but the brains of adults are also “plastic” to a degree. There is evidence that, in patients with brain damage, healthy brain areas can take over for injured areas and adopt new functions.
