- 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.
- No invasion
- - 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.
