• Functional magnetic Resonance Imaging

  FMRIs detect the changes in both blood oxygenation and flow that occur as a result of neural activity in specific parts of the brain. When an area is more active it uses more oxygen and blood flow is increased. FMRI produces 3D images showing which parts of the brain are involved in particular mental processes, and this has important implications for our understanding of the localisation of function.
• EEG


  EEGs measure electrical activity within the brain via electrodes that are fixed to an individual's scalp using a skull cap. The scan recording represents the brainwave patterns that are generated from the action of thousands of neurons providing an overall account of brain activity. EEG is often used by clinicians as a diagnostic tool as unusual arrhythmic patterns of activity may indicate neurological abnormalities such as epilepsy, tumours or sleep disorders.
