Comprised of the brain and spinal cord.
Central Nervous System (CNS)
Measures the electrical activity of the brain to diagnose seizure disorders, epilepsy, and tumors.
Electroencephalogram (EEG).
Chronic brain disorder characterized by recurrent seizure activity.
Epilepsy.
The macroscopic cord-like collection of fibers (axons and dendrites) that carry electrical impulses.
