Final answer:
The supplementary motor cortex is involved in planning and coordinating movements. If it is removed, the brain can compensate for the loss over time. Recovery can vary in speed and can be facilitated through physical therapy and rehabilitation.
Step-by-step explanation:
The supplementary motor cortex is involved in planning and coordinating movements, as well as managing sequential movements based on prior experience. If it is removed, it can lead to difficulties in planning and initiating movements. However, the brain has the ability to reorganize and compensate for the loss, resulting in recovery over time.
The speed of recovery can vary depending on several factors, including the individual's age, overall health, and the extent of the injury. Recovery can range from weeks to months or even longer. Physical therapy and rehabilitation can help facilitate the recovery process by promoting the development of alternative neural pathways.
