What is EEG?

Electroencephalography (EEG) is a neurophysiological monitoring method to record electrical activity of the brain. It is typically non-invasive, with electrodes placed along the scalp. EEG is commonly used to diagnose epilepsy, sleep disorders, and other neurological conditions. It can also be used in research to study brain activity during various cognitive processes.

What other technologies are related to EEG?

EEG Competitor Technologies

fMRI

Functional Magnetic Resonance Imaging (fMRI) measures brain activity by detecting changes associated with blood flow. It offers higher spatial resolution than EEG but lower temporal resolution, serving as an alternative method for studying brain function.

fNIRS

Functional Near-Infrared Spectroscopy (fNIRS) is a neuroimaging technique that measures brain activity through hemodynamic responses. It's a competitor as it provides an alternative non-invasive way to measure brain activity, although it has different strengths and weaknesses compared to EEG.

MEG

Magnetoencephalography (MEG) measures brain activity by detecting magnetic fields produced by electrical currents in the brain. Like EEG, it has high temporal resolution but measures different aspects of brain activity, thus a direct competitor.

electrocorticography

Electrocorticography (ECoG) involves placing electrodes directly on the surface of the brain to record electrical activity. It provides higher spatial resolution and signal-to-noise ratio compared to scalp EEG, acting as a more invasive alternative.

EEG Complementary Technologies

EP

EP is short for Evoked Potentials. Evoked potentials are electrical potentials recorded from the nervous system following presentation of a stimulus. EEG is often used to measure Evoked Potentials.

EOG

Electrooculography (EOG) measures eye movements. It is often used in conjunction with EEG, especially in sleep studies or to correct for eye movement artifacts in EEG data.

PSG

Polysomnography (PSG) is a comprehensive sleep study that includes EEG, EOG, EMG, and other measures. EEG is a core component of PSG, so PSG is complementary.
