Glossokinetic artifact is classified as which type of artifact?

Glossokinetic artifact is classified as a biological artifact. This type of artifact is produced by physiological movements or activities of the body. Specifically, glossokinetic artifact occurs due to the movement of the tongue, which can create electric potentials that mimic or obscure brain activity on an EEG. Therefore, it is categorized under biological artifacts because it arises from the natural, involuntary activities of the body rather than external factors or mechanical influences.

Recognizing glossokinetic artifact as a biological phenomenon is crucial for accurate EEG interpretation. Being able to differentiate between biological artifacts and other artifact types helps in properly analyzing EEG data and ensures that clinicians can distinguish genuine brain activity from signals that are a result of bodily movements.
