Clinical Scenario: Brain Injury

After a small, localized brain injury, a patient finds they can no longer purposefully wiggle their left toes on command. They can still feel when their toes are touched, and they understand the instruction perfectly, but they cannot seem to send the correct signal to initiate the specific, voluntary action. Based on this isolated symptom, which functional area of the brain was most likely damaged? Explain your reasoning.
