EEG (electroencephalogram) - Mayo Clinic An EEG records the electrical activity of the brain through electrodes put on the scalp EEG results show changes in brain activity This may help diagnose brain conditions such as epilepsy and other seizure conditions
EEG Results: Normal vs Abnormal Brain Waves (2026) Normal EEG results show organized, symmetric patterns appropriate for your age and state of consciousness, while abnormal findings may indicate epileptiform activity, background slowing, or structural brain changes
EEG vs MRI: What Can an EEG Show That an MRI Cannot? EEG can measure the brain’s real-time responses to external stimuli through evoked potentials like light, sound, or touch These tests are especially useful for evaluating sensory processing and certain forms of neuropathy
Electroencephalography (EEG) - Epilepsy Program | Barrow Neurological . . . Electroencephalography (EEG) is a diagnostic test that measures the electrical activity of the brain During EEG, small metal discs called electrodes are pasted to the scalp to detect the tiny electrical signals produced by brain cells when they communicate
What Does an EEG Graph Show About Your Brain’s Activity? The EEG graph displays various brainwave patterns, which are categorized by their frequency, measured in Hertz (Hz), and reflect different states of consciousness or brain activity
