fMRI of Optokinetic Eye Movements With and Without a Contribution of Smooth Pursuit

Optokinetic eye movements are elicited when tracking a moving pattern. It can be argued that a moving pattern of stripes invokes both the optokinetic and the smooth pursuit eye movement system, which may confound the observed brain activation patterns using functional magnetic resonance imaging (fMRI). A moving pattern of limited‐lifetime‐dot stimulation does not target the smooth pursuit eye movement system.
