Which diagnostic test records the electrical activity of the brain?

Explanation:
Recording the brain’s electrical activity is done with an electroencephalogram, or EEG. Electrodes placed on the scalp pick up the brain’s electrical waves, producing patterns that help diagnose seizures, sleep disorders, and other brain conditions. The electrocardiogram measures the heart’s electrical signals, the electromyogram records muscle activity, and gastrology relates to the stomach and digestive system rather than brain activity. So the EEG is the test that directly records the brain’s electrical activity.
