home / medterms medical dictionary a-z list / neuroplasticity definition Medical Definition of Neuroplasticity Neuroplasticity: The brain's ability to reorganize itself by forming new neural connections throughout life. Neuroplasticity allows the neurons (nerve cells) in the brain to compensate for injury and disease and to adjust their activities in response to new situations or to changes in their environment. Brain reorganization takes place by mechanisms such as axonal sprouting in which undamaged axons grow new nerve endings to reconnect neurons whose links were injured or severed.
