We will show your child 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.
Your child will need to lie very still with eyes closed and try to relax. Some children have difficulty lying still for the electrode placement. When this happens, the child may be swaddled or placed on a papoose board during the electrode placement. After the electrode placement is finished, the parents may hold the child. Other visitors can wait in the waiting room.
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. We may ask your child to breathe deeply for 2-3 minutes during the test.
