AO3 - EEG

• Allows direct measurement of neural activity.


  Strength - EEG
• Good at detecting synchronised activity in the brain that occurs when people sleep or have seizures. 


  Strength - EEG
• Does not give much information about which neurons generate the electrical signals.

  Limitation - EEG
• Can only pick up electrical activity from the cortex (surface level)


  Limitation - EEG
• Hard to interpret because electrical signals detected by electrodes are small


  Limitation - EEG
• High temporal resolution - real time recording of brain activity.


  Strength - EEG
• Takes account for networked nature of the brain - measuring electrical activity can provide insight to how the brain functions as a whole.


  Strength - EEG
• Records general brain activity which cannot pinpoint specific responses and the exact source of brain activity.

  • Failed to improve our understanding of localisation.


  Limitation - EEG
