Brain • Electroencephalography •
An electroencephalogram (EEG) is
a recording of brain activity
During this painless test, small sensors are attached to
the scalp to pick up the electrical signals produced by the brain.
These signals are recorded by a machine and are looked at by a doctor.
An EEG is a test that detects
abnormalities in your brain waves, or in the electrical activity of your brain
Most waves of 8 Hz and higher frequencies are normal findings in the EEG of an awake adult.
