Your child will be shown what will happen. Electrodes (referred to as buttons, with wires) are placed on areas of the child's head with cream, after cleaning each area with a cotton tip.
The child is asked to lie very still with his / her eyes closed and told to try to relax. The electrodes pick up signals about how the brain is working. These messages are sent to a computer which records the activity.
During part of the test, the technologist flashes a bright light in front of the child for 10 seconds approximately nine different times. Some children will be asked to breathe deeply for 2-3 minutes during the test.
The technologist may ask parents to hold younger children during the test to get a better recording. Other visitors can wait in the waiting room.
