Roadmap to EEGs: EEG Artifacts - YouTube

Splet26. dec. 2011 · Artifacts in electroencephalography (EEG) are electrical potentials of nonbrain origin that may be challenging to interpret. Artifacts can be physiological in origin (i.e., derived from electrophysiological properties of other organs) or they can be nonphysiological, resulting from electrical activity of environmental origin. SpletAbstract. Artifacts are ubiquitous in EEG, and can significantly affect EEG interpretation. Artifacts may mimic pathological abnormalities, and may obscure the underlying EEG; … SpletFor eg, during an EEG session, a blink activity was reported by Channel 3 and the corresponding Event-Related Potential was also raised. Thus, this activity induced an artifact in EEG data. Now we have to eliminate this artifact from EEG signal to get the original signal.
