Oculomotor Systems and Perception Understanding visual

Oculomotor Systems and Perception. Understanding visual experience has long challenged the best of human minds, from the Ancient Greeks' interest in optics to the study of visual perception by contemporary psychologists and neuroscientists . Today's scientific study of perception seeks to understand the nature of our ...


Basics of seeing motion

Keywords: Motion perception; Afferent/efferent mechanisms; Oculomotor system; Apparent motion; Velocity transposition; Motion extrapolation. This chapter is about basic conditions of seeing motion (mostly of single objects in the frontoparallel plane). It emphasizes the richness and challenge of phenomena in motion ...


Microsaccades: a microcosm for research on oculomotor control

oculomotor control, visual perception, and the allocation of attention. Keywords: fixational eye movements; microsaccades; random walk; visual perception; covert attention. Introduction. Visual perception is based on motion. This fact is obvious for some nervous systems in animals: a resting fly is invisible to a frog.


A review of the role of efference copy in sensory and oculomotor

A review of the role of efference copy in sensory and oculomotor control systems ... In the oculomotor system it provides the only extraretinal signal about eye position that is available without delay, and it is shown to be the most important extraretinal ... It functions differently for perception and for visually guided behavior.

Anticipation of physical causality guides eye movements

and after a collision of two moving objects the oculomotor system implicitly predicts upcoming physically plausible target trajectories. Keywords: Causality perception, saccades, smooth pursuit.

Dynamics of the vestibular system and their relation to motion

physiology of the human vestibular system and its interconnection with the oculomotor system. utricles (otolith organs) and the relation between subjective perceptions of motion and the accelerations which produce them are studied. matical models of the dynamic functions of the vestibular system are presented.

When a fixation point moves under a row of identical targets at a speed of one target for each flash of a strobe, smooth apparent movement of the  ...


evoked responses in relation to visual perception and oculomotor

chophysiological investigations, the visual system has been used exten- sively for the study of phenomena associated with perception. In the present report, results are described and discussed from experiments in which responses evoked by visual stimuli are studied in relation to oculo- motor reaction times, and in relation ...

Lecture 13: Oculomotor System. “Eyes are the window to the soul”??? In any case, eye movements are strongly linked to perception and higher cognitive functions such as attention and decision- making. Eye movements provide an ideal model system to study the sensory-motor transformations that lead from perception to ...


Depth and Size Perception

ing images from each retina. In this chapter, we consider the three major factors in depth perception: oculomotor cues, monocular cues (including motion cues), and binoc- ular cues. We start this survey with the oculomotor cues. FIGURE 7.1 Our visual systems must re-create the 3D world using an essentially flat, 2D retina.
