  • Doesn't rely on radiation, so it's risk-free, non-invasive, and simple to use. 
  • Images have high spatial resolution (detail by the millimeter) and provides clear picture of how brain activity is localised.

  • Expensive compared to other neuroimaging techniques.
  • Requires patient to stay still for detailed image.
  • 5 second time-lag between image and firing of neuronal activity.

  • Addresses limitations of EEG - more specific.
  • Good temporal resolution.

  • Lack of standardisation between different research studies - makes it difficult to confirm findings.
  • Background noise and extraneous material must be completely eliminated.

  • Provided foundation understanding of key processes in the brain.
  • Broca & Wernicke depended on it for establishing links between language, brain, and behaviour.
  • Improve medical knowledge and help generate hypotheses.
