• Functional magnetic resonance (fMRI) A brain scanner which measures increased blood flow to brain sites when individuals are asked to perform cognitive/physical tasks. Increased blood flow indicates increased demand for oxygen in that area
• fMRI can help build up a map of brain localisation. fMRI generates 3D images that can be used to locate the exact source of mental activities within the brain
• Electroencephalograms (EEGs) Measures electrical activity of neurones in the brain using electrodes attached to the scalp, and measures how electrical activity in the brain varies over time/in different states (e.g. waking vs. asleep).
