  1. Your head is measured to aid in the placement of the electrodes to measure your brain activity. An electrode is a wire with a small “cup” or flat end. First the skin on your scalp is cleaned with an exfoliant. The cup end will be attached to your scalp with a special paste.
  2. More electrodes are placed on your chin and near your eyes. These will help monitor what kind of sleep you are having based on the movements of your facial features.
