An ınstrument that measures electrical potentials on the scalp and generates a record of the electrical activity of the brain. Also called encephalograph
Electroencephalogram, electric waves from the brain The EEG is recorded by surface electrodes from the scalp It exhibits characteristic modulations during sleep
Say: uh-lec-tro-en-sef-a-la-gram Doctors can see inside your brain with a special machine that makes an electroencephalogram, or brain wave picture Believe it or not, no matter what you're doing (even sleeping!), your brain gives off electric waves An electroencephalogram machine measures these electricity waves and takes a picture of them to show where and how big they are Pretty neat, huh? Some kids have a lot of extra electricity flowing inside their brain, which can cause things called seizures But getting an electroencephalogram is no big deal; it doesn't hurt, and imagine the cool brain waves you'll be able to see when you're done!
Amplification and recording of the electrical activities of the brain This test can be helpful in ruling out epilepsy or localizing lesions in the cerebrum
– a diagnostic procedure where special pieces of material are placed on the scalp or fine needles placed in the brain to record electrical activity in the brain
