Brain Plasticity and Vision

Did you know that patients who had gone partially blind as a result of suffering a stroke were able to regain some vision through exercise? The patients did about 300 exercise-tests at a time, sitting in front of a computer for 15 to 30 minutes once or twice a day, every day, for nine to 18 months. The work was exhausting but it did help them to regain some vision, showing that the brain may have even more plasticity than was originally believed.
