Examples of Electroencephalography in the following topics:

  • Brain Imaging Techniques

    • Electroencephalography (EEG) is used to show brain activity in certain psychological states, such as alertness or drowsiness.

  • Association Areas

    • Well-known techniques are EEG (electroencephalography), which records the brain's electrical activity, and fMRI (functional magnetic resonance imaging) , which tells us more about brain functions.

  • Medical Imaging

    • Measurement and recording techniques which are not primarily designed to produce images, such as electroencephalography (EEG), magnetoencephalography (MEG), electrocardiography (EKG), but which produce data susceptible to be represented as maps (i.e. containing positional information), can be seen as forms of medical imaging.

  • Stages of Sleep

    • In electroencephalography, the REM phase of sleep is easily identified by its paradigmatic fast, small-amplitude waves.
