  • fMRI Scanning 1990 (functional Magnetic Resonance imaging)
    • Uses strong magnetic field and radio waves to create detailed images.
    • Looks at blood flow in the brain to detect areas of activity.
    • No radiation involved in this procedure.
    • The scanner sends information to a computer that is then able to create a map of action to show changing levels of neural activity in different brain areas as tasks are being completed.
    • + No danger from radiation, unlike CAT Scanning and to an extent PET Scanning.
      • No invasion
        • No radiation exposure
      • The detection of blood flow is very precise, slight changes could be detected.
        • Good at detecting issues around stroke
      • Good at looking at brain structure and functioning when it comes to learning about the brain.
    • - Cannot look at actual receptors of neurotransmitters.
      • To much head movement can distort the imaging, this could be a problem
      • not easy to gather a baseline measure as brain is never at rest.
      • Those who have pacemakers a and more generally will have an issue such as claustrophobic.
      • Scanning is not risk free, for example, there can be tingling felt when magnetic fields switch during the scan.
