Neuroplasticity describes the brain’s ability to reorganize its structure and function in response to experience, learning, or injury. This means neural connections can be strengthened or weakened, new synapses can form, and brain regions can take over functions when another area is damaged. The idea of changing the brain across the life span in response to both new learning and injury fits neuroplasticity—it's the mechanism behind skill acquisition (like learning a new instrument) and recovery after brain injury. Other concepts don’t capture this dynamic reorganization: hemispheric specialization refers to certain functions being predominantly processed in a particular hemisphere, contralateral control describes how motor commands cross to the opposite side of the body, and the nervous system is the entire network rather than a process of change.
