Ways of studying the brain AO3

• fMRI


  strength - non invasive and has high spatial resolution

  weakness - expensive, pp must stay perfectly still, poor temporal resolution, doesn't measure activity of individual neurons
• EEG


  strength - effective diagnosing condition for epilepsy, high temporal resolution, non invasive but may cause some discomfort (electrodes attached to scalp)

  weakness - cant pinpoint exact source of neural activity, poor spatial resolution
• ERP


  strength - non invasive, high temporal resolution, same as EEG

  weakness - not standardised and there is differentiation in procedure of how ERPs are used
• Post-mortem


  strength - improves medical knowledge (Brocas and Wernickes). technically non invasive

  weakness - ethical? cant establish causation or extraneous factors (maybe the damage found was because of old age
