Review the essentials
What you should now know
Neurology studies the nervous system, which includes the brain, spinal cord, nerves, and muscles. Neurons communicate through electrical and chemical signals. The brain controls thinking, movement, sensation, and essential life functions. Neurologists use history, exam, and tests to find where a problem is located and how to treat it.
