The article discusses a medical condition involving a 21-year-old man suffering from mirror movements. The results of several medical tests administered on him including physical examinations, magnetic resonance imaging (MRI) of the brain, thyroid functions, and electroencephalography appears normal. His condition is explained by the abnormal connection between the primary motor cortex and both sides of the spinal cord.
