After suffering a severe brain injury in a dirt-bike accident that permanently damaged much of his right motor cortex, 9-year-old amir was partially paralyzed on the left side of his body. amazingly, after several months of intensive physical therapy, he partially regained the use of his left leg and left arm. this example best illustrates the principle of:

principle of neuroplasticity.

In the result of the brain damage, amir stopped moving the left side of his body and after rehabilitation he partially regained its functions. Why?  because of neuroplasticity. The brain, especially in children, has the ability of being plastic, meaning that the brain activity associated with a given function, can be transferred to a different location. This process is achievable through rehabilitation.
