It confirms the fundamental involvement of the magnocellular pathway and the mediating role of retinal temporal frequency in intra-saccadic motion perception. Perceptual efficacy is maximized within a specific temporal frequency bandwidth aligned with the tuning properties of magnocellular motion detectors. These perceptual phenomena are tightly coupled with individual oculomotor kinematics, such as saccade peak velocity and post-saccadic oscillations, demonstrating that eye movement dynamics are integral modulators of intra-saccadic visual processing.
