Neuroimaging

• Positron Emission Topography (PET)


  Radioactive substance (glucose) injected into bloodstream.

  Provides info on the active brain's function + location, through color
• Magnetic Resonance Imaging (MRI)


  Harmless Magnetic fields + radio waves to produce images of the brain structure
• Functional Magnetic Resonance Imaging (fMRI)


  Harmless Magnetic fields + radiowaves

  Monitors blood flow + oxygen consumption = revealing brain's function + activity
• Electroencephalogram (EEG)


  Measures electrical activity in the brain

  Uses electrodes on the scalp to detect the brain waves.
• Phrenology


  Study that the size + shape of skull = personality + intelligence
