Anticipatory smooth pursuit eye movements evoked by probabilistic cues.
Anticipatory smooth eye movements (ASEM; smooth eye movements in the direction of anticipated target motion) are elicited by cues that signal the direction of future target motion with high levels of certainty. Natural cues, however, rarely convey information with perfect certainty, and responses to uncertainty provide insights about how predictive behaviors are generated. Subjects smoothly pur...
متن کاملAnticipatory Gain Modulation in Preparation for Smooth Pursuit Eye Movements
We studied the effect of the probability of required tracking on the gain of visuomotor transmission for pursuit initiation in monkeys. We recorded the ocular responses to a brief movement (perturbation) of a target located at an eccentric position from the central fixation spot. As soon as the central fixation spot went off, the animal was required to make a saccade to the target if it remaine...
متن کاملAnticipatory saccades in smooth pursuit: Task effects and pursuit vector after saccades
The dramatic improvement in smooth pursuit performance seen while analyzing the pursuit target has been ascribed to attention enhancement. With a periodic constant velocity target trajectory we ran a concurrent listening condition instead, to see if this mild distraction would degrade performance. Performance improved somewhat with the listening task, suggesting that displacing attentional effo...
متن کاملEye Fields Stimulation Facilitates Anticipatory Pursuit
Missal, M. and S. J. Heinen. Supplementary eye fields stimulation facilitates anticipatory pursuit. J Neurophysiol 92: 1257–1262, 2004. First published March 10, 2004; 10.1152/jn.01255.2003. Anticipatory movements are motor responses occurring before likely sensory events in contrast to reflexive actions. Anticipatory movements are necessary to compensate for delays present in sensory and motor...
متن کاملQuick phases control ocular torsion during smooth pursuit.
One of the open questions in oculomotor control of visually guided eye movements is whether it is possible to smoothly track a target along a curvilinear path across the visual field without changing the torsional stance of the eye. We show in an experimental study of three-dimensional eye movements in subhuman primates (Macaca mulatta) that although the pursuit system is able to smoothly chang...
