  • 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.
