Question 2

Explain neural plasticity in the brain, in the context of recovery from injury.

Accepted Answer

Areas of the brain involved in a body part that is removed, such as following a limb amputation, are taken over by ingrowth of synaptic connections from nearby areas, rather than the areas disappearing along with the limb.Skills present on one side of the cerebral cortex can be developed on the other side, as might happen if a right-handed person must become left-handed, or large areas of the brain are removed as treatment for epilepsy.
