The brain is not hard-wired; rather, it is changing all the time. Neuroplasticity refers to the inherent ability of the brain to change its connections in response to experiences, including when it is injured. When the brain is injured, functions that were performed by the damaged area are lost. However, over time, and with practice and rehabilitation, uninjured parts of the brain can take over some, or all of those lost functions. The brain does this by rewiring itself, either by using alternative pathways or by sprouting new ones.
