AO3

• fMRI Pros:

  • high spatial resolution - 4 images a second
  • can be used while a patient completes a task
  • does not use ionising radiation unlike PET

  Cons:

  • Poor temporal resolution - 5 second delay between neuronal activity and produced image
• EEG Pros:

  • Useful for investigating characteristics of sleep
  • higher temporal resolution than fMRI
  • useful in the diagnosis of epilepsy

  Cons:

  • Lower spatial resolutions than fMRI
• Post Mortem examination Pros:

  • Useful for medical and further knowledge eg. Tan

  Cons:

  • Ethical issues - patients can't always give informed consent before they die
  • Potentially reductionist as it can incorrectly create a cause and effect relationship when it could be to another factor eg. drug use
• EEG vs ERP:

  • EEG is a recording of general brain activity usually linked to states such as sleep and arousal, whilst ERPs are elicited by specific stimuli presented to the participant
