  • Neuroimaging either directly or indirectly image the structure, function, or pharmacology of the brain.
  • Structural imaging and functional imaging.
    • Structural imaging- structure of the brain and the diagnosis of large-scale intracranial disease (such as a tumor) , as well as injury.
    • Functional imaging- diagnose metabolic diseases and lesions on a finer scale (such as Alzheimer՚s disease) , and also for neurological and cognitive-psychology research.
      • Allows the brain՚s information processing to be visualized directly.
  • EEG shows brain activity (alertness or drowsiness)
  • PET scans show brain processes by using the sugar glucose in the brain.
  • MRI scans echo waves to discriminate among grey matter, white matter, and cerebrospinal fluid.
  • Functional MRI scans measure brain function via a computer՚s combination of multiple images taken less than a second apart.
