An electroencephalogram (EEG) is a test that
measures and records the electrical activity of your brain. Special sensors
(electrodes ) are attached to your head and hooked by
wires to a computer. The computer records your brain's electrical activity on
the screen or on paper as wavy lines. Certain conditions, such as
seizures, can be seen by the changes in the normal
pattern of the brain's electrical activity.
