12. Brain Imaging Techniques Methodology What is imaged? How? Electroencephalography (EEG) Changes in electrical brain current Electrodes placed on scalp measure electrical brain waves Computed (Axial) Tomography Scan (CT or CAT) X-ray images of the brain Multiple images (tomograms) are taken by rotating X-ray tubes. Does not image function Positron Emission Tomography (PET) Emissions from radioactive chemicals in the blood Radioactive isotopes injected into the blood are detected like X-rays Magnetoencephalography (MEG) Changes in electrical brain current Similar to EEG but magnetic brain waves are measured instead of electrical waves Functional Magnetic Resonance Imaging (fMRI) Blood flow; oxyhemoglobin to deoxyhemoglobin ratio Relies on magnetic properties of blood. Shows brain function spatially and temporally
