Have you ever heard that once a brain cell has been damaged that it can never be repaired? Research has proven that this is not true.
The brain can actually change, new dendrite pathways can be generated and parts of the brain can be stimulated to reorganize and function differently.
This concept is called Neuroplasticity. This is the 'plastic' attribute to the brain's structure and explains how this squishy, blob of electrical impulses in our head can actually grow, can calm down, and can actually CHANGE.
