Physiological and non-physiological EEG artifacts

Abstract

Artifacts are signals recorded on the electroencephalogram that are not cerebral in origin and can be divided into physiological and non-physiological artifacts. Physiological artifacts are generated from the patient itself and include cardiac, glossokinetic, muscle, eye movement, respiratory and pulse artifact among many others. The EEG recording can be contaminated by numerous non-physiological artifacts generated from the immediate patient surroundings. Common non-physiological artifacts include those generated by monitoring devices, infusion pumps and suctioning devices though electrical devices like mobile phones may also contaminate the EEG record 1.
