Strength

• EEG has proved invaluable 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
• Similarly it has contributed much to our understanding of the stages involved in sleep
• 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 (and even less in some cases)
