Effects of eye movements on image registration. A: SPM99 registration parameters for two concatenated runs totaling 160 images. Note the large amount of rotational movement (yaw, in red) corresponding to the movement of the stimulus. B: Registration parameters after excluding eye movement information. A reduction the amplitude of most movement parameters, particularly yaw, is observed.
