Eye blinks will generate
muscle artifacts in the
frontopolar locations (Fp1
and Fp2) and less so in
frontal sensors (F3/F4, F7/F8),
overshadowing brain activity
in EEG recordings.
Blinks
Moving the eyes will generate
muscle artifact in the forehead
and front of the head. A high
concentration of neurons
in the eyes generate strong
electromagnetic elds, so eye
movement causes disruptions
in the EEG recording.
