    • Strength:
      • EEG has been useful in studying the stages of sleep and in the diagnosis of conditions such as epilepsy, a disorder characterised by random bursts of activity in the brain that can easily be detected on screen.
      • Unlike FMRI, EEG technology has extremely high temporal resolution.
      Today's EEG technology can accurately detect brain activity at a resolution of a single millisecond
      This shows the real-world usefulness of the technique.
    • Limitation:
      The main drawback of EEG lies in the generalised nature of the information received (that of many thousands of neurons).
      The EEG signal is also not useful for pinpointing the exact source of neural activity. Therefore it does not allow researchers to distinguish between activities originating in different but adiacent locations.
