Splet11. apr. 2024 · Sweat artifacts pose a frequent challenge in electroencephalography (EEG) recordings, significantly impacting the clarity and readability of the EEG signals. These artifacts arise when the body’s natural sweat response alters the skin’s conductivity, leading to interference with the electric signals detected by the electrodes. 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.
