EEGs

• What does EEG stand for?

  Electroencephalogram
• What does an EEG do?


  Shows electrical activity in the brain
• How does the EEG work?


  Using electrodes that measure brain waves from action potentials of neurones
• What are some strengths of EEGs?

  • Can diagnose disorders
  • Non-invasive
  • High temporal resolution
• What are some weaknesses of EEGs?

  • Information is generalised
  • Poor spatial resolution, cannot localise source of activity
