What to Expect During Your Test

  • During your Electroencephalography test electrodes will be attached to your scalp. The electrodes carry the electrical energy of your brain to a machine so that it can be read.
  • You may be asked to do things like open and close your eyes, or change how you are breathing, and we may flash bright lights or make noises. These are things that may cause changes in the electrical energy of your brain so that we can measure them.
  • You will not feel any discomfort
