Gaze-, eye-, and head-movement dynamics during closed- and open-loop gaze pursuit.
Horizontal step-ramp stimuli were used to examine gaze-, eye-, and head-movement dynamics during head-unrestrained pursuit in two rhesus monkeys. In a first series of experiments, we characterized and compared head-restrained (HR) and -unrestrained (HU) pursuit responses to unpredictable, nonperiodic, constant velocity (20-80 degrees/s) stimuli. When the head was free to move, both monkeys used...
متن کاملThe interaction of visual, vestibular and extra-retinal mechanisms in the control of head and gaze during head-free pursuit
The ability to co-ordinate the eyes and head when tracking moving objects is important for survival. Tracking with eyes alone is controlled by both visually dependent and extra-retinal mechanisms, the latter sustaining eye movement during target extinction. We investigated how the extra-retinal component develops at the beginning of randomised responses during head-free pursuit and how it inter...
متن کاملHuman head-free gaze saccades to targets flashed before gaze-pursuit are spatially accurate.
Previous studies have shown that accurate saccades can be generated, in the dark, that compensate for movements of the visual axis that result from movements of either the eyes alone or the head alone that intervene between target presentation and saccade onset. We have carried out experiments with human subjects to test whether gaze saccades (gaze = eye-in-space = eye-in-head + head-in-space) ...

متن کاملEye-Pursuit and Reafferent Head Movement Signals Carried by Pursuit Neurons in the Caudal Part of the Frontal Eye Fields during Head-Free Pursuit
Eye and head movements are coordinated during head-free pursuit. To examine whether pursuit neurons in frontal eye fields (FEF) carry gaze-pursuit commands that drive both eye-pursuit and head-pursuit, monkeys whose heads were free to rotate about a vertical axis were trained to pursue a juice feeder with their head and a target with their eyes. Initially the feeder and target moved synchronous...
