This shows the brain fibers that travel from the cortex to the lower brain, including fibers that control movement of leg, arm and hand. The uninjured side of the patient’s brain is in green. The injured side is in yellow and shows the fiber loss that has led to the patient’s difficulty moving his left arm and hand.
