fMRI

• fMRI shows brain activity
• 3D scans providing structural and functional information
• Changes in brain activity happen by strong magnetic field
• 1. More oxygenated blood flows in active areas
  2. Molecules in oxygenated blood respond differently to a magnetic field
  3. More active areas of brain can be identified
• fMRI usage

  1. Research function of brain. Ps carry out task in scanner, part of the brain more active is coloured
  2. Used to diagnose medical problems show damaged or diseased areas of brain
  3. Abnormal activity in the brain
• non-invasive technique
