BACKGROUND
Electroencephalography is an electrophysiological monitoring method to record the electrical activity of brain. This uses invasive electrodes, measures the voltage fluctuations resulting from iconic current within the neurons of the brain.1
The aim of the experiment is to methods of recording and identification of different types of EEG waves.

PROCEDURE
The EEG headband is worn by the subject, and the globs of electrode gel are placed underneath the metal patches. If the kit is new, place the black alligator clip behind the ear and the red one on the back of the head and the orange interface cable in the orange port on the heart and brain spike box and the other end to the computer. The patient is asked to hold still till the recording is complete. The subject is asked to open and close the eyes every 10 seconds. The red record button is pressed on the spike recorder software to record the data. The each event is marked using an event marker by pressing a number during the recording.2
