Primate vision is severely constrained by the fact that fine details in a visual scene can only be resolved by the fovea, where acuity is greatest. This tiny portion of each retina, which amounts to less than half of 1 degree of visual angle, must be moved around and positioned on behaviorally relevant stimuli in order to facilitate visual perception. Saccadic eye movements (saccades) reposition the direction of gaze (and the fovea) some three to five times per second and provide the means by which detailed visual information is accumulated during visual scanning. The ability to move the eyes accurately and precisely among targets of interest is crucial to adaptive behavior. This chapter shows that the neural mechanisms involved in mobilizing the fovea and the focus of attention together are also involved in moving attention by itself.
