What causes glossokinetic artifact?

Glossokinetic artifact is specifically associated with the movement of the tongue. This type of artifact arises during an EEG recording when the tongue's motion generates electrical signals that can be detected by the electrodes on the scalp. It is important to understand this phenomenon because the tongue is a muscle, and its movements can produce electrical activity, which can interfere with the accurate interpretation of brain wave patterns captured in an EEG.

In EEG practice, recognizing and managing artifacts is crucial, as they can mimic or obscure brainwave activity, leading to potential misdiagnosis or misinterpretation. Thus, understanding the source of specific artifacts, like glossokinetic artifact, enables technicians and clinicians to differentiate between true neural activity and movement-related disturbances. This knowledge is particularly valuable in ensuring the highest quality of EEG results, as it allows for appropriate adjustments during the recording process and analysis.
