Linked target selection for saccadic and smooth pursuit eye movements.
In natural situations, motor activity must often choose a single target when multiple distractors are present. The present paper asks how primate smooth pursuit eye movements choose targets, by analysis of a natural target-selection task. Monkeys tracked two targets that started 1.5 degrees eccentric and moved in different directions (up, right, down, and left) toward the position of fixation. ...
متن کاملSmooth pursuit eye movements in response to predictable target motions.
The human smooth pursuit eye movement system has a latency of about 150 msec. However, this study shows that humans can learn to perform zero-latency tracking of targets that move with continuous velocity and amplitude-limited acceleration. Superposition of eye velocity and target velocity records, for our unique target waveforms, demonstrated that the subject was using the correct waveform and...
متن کاملPrediction of saccadic amplitude during smooth pursuit eye movements
If humans try to pursue a moving target, the nervous system uses predictions to overcome some of the nervous systems delays. It is therefore possible for the eyes to pursue a target with virtually no delay and to make accurate catch-up saccades to moving targets. Another example of a delay is the latency of a saccade made in response to a target step. Due to imperfect pursuit, the retinal error...
متن کاملTarget Selection by the Frontal Cortex during Coordinated Saccadic and Smooth Pursuit Eye Movements
Oculomotor tracking of moving objects is an important component of visually based cognition and planning. Such tracking is achieved by a combination of saccades and smooth-pursuit eye movements. In particular, the saccadic and smooth-pursuit systems interact to often choose the same target, and to maximize its visibility through time. How do multiple brain regions interact, including frontal co...
