In an EEG, an artifact refers to any abnormal signal that is not produced by brain activity, such as muscle movements, eye blinks, or external interference in the recording. Artifacts can affect the accuracy of the EEG readings and may need to be identified and removed during data analysis.

Why does artifact always appear ahead of action potential?

Artifacts appear ahead of action potentials on an EEG because they are typically due to external interference or movement-related signals, which are faster and more prominent than the electrical signal generated by the action potential. Artifacts can distort the recording of brain activity and need to be identified and removed to accurately interpret the EEG data.
