Etymology

Origin of neuroplasticity

First recorded in 1970–75; neuro- + plasticity

Explanation

Neuroplasticity refers to the ability of our brain and nervous system to adapt, grow, and change in response to stimuli. The brain reorganizes itself, forming new connections between neurons in response to learning, new experiences, and even injury. Neuroplasticity includes two main mechanisms: Functions can be moved to different parts of the brain when one part is damaged, and the physical structure of the brain can change due to learning. Connections and pathways between neurons strengthen or weaken to make our brains more efficient. Neuroplasticity also involves making new neurons in the part of the brain responsible for memory and learning. Learning a new language can actually increase the size of the areas of the brain associated with language and speech.
