Ways Of Studying The Brain AO1

• FMRI


  Magnetic field/radio waves used to monitor blood flow, which measures changes in energy released by haemoglobin and shows brain activity (oxygen consumption)
• FMRI


  • Gives a moving picture of the brain
  • Can look at specific areas by comparing baseline task and specific activity
• EEG


  Electrodes put on the scalp to detect neuronal activity directly below where they are placed
• EEG


  • Different numbers of electrodes depending on research focus
  • Measures brain waves in amplitude and frequency
• ERP


  Electrodes put on the scalp to detect neuronal activity directly below where they are placed in response to a stimulus introduced by the researcher
• ERP


  • Uses statistical averaging to filter out extraneous brain activity not linked to the stimulus
• Post-mortem


  Brain examined after death to try and correlate structural abnormalities/damage to behaviour whilst they were alive
