An electroencephalogram (EEG) is a test which tracks and records brain wave patterns. Small metal discs with thin wires called electrodes are placed on the scalp, and these electrodes send signals to a computer to record the results.
An EEG can be done while the child is seated in a chair. A research assistant will attach electrodes to different locations on the scalp using adhesive paste. Each electrode is connected to an amplifier and EEG recording machine. The electrical signals from the brain are converted into wavy lines on a computer screen. It is important to sit extremely still because movement can change or effect the results.
EEGs are very safe and individuals do not feel any shocks on the scalp or elsewhere during the test. If you have any questions about the EEG procedure, you can email email@example.com, or ask the research assistant during the course of the experiment who will be more than happy to answer any queries.
