Ways Of Studying The Brain

• FMRI

  Detects blood flow in the brain. Active areas are compared with low activation areas and displayed on an fmri image
• FMRI evaluation

  • Good spatial resolution
• Post mortem

  Brains are cut to give a firmer texture. Unusual brains are cut and compared to healthy brains
• Post mortem evaluation

  • Good spatial resolution
  • Good temporal resolution
• ERP


  Presents a stimulus multiple times. Creating a smooth count of activation by combining data
• EEG

  22-34 electrodes attached to a cap and fitted on scalp. Each electrode shows the sum total of activation
• EEG evaluation

  • Historically important
  • Cheap
