Adaptation of reactive saccades in normal children.
PURPOSE To compare the amount, the retention, and the extinction of saccadic adaptation in two groups: 9 adults (23-36 years old) and 9 children (11-14 years old). METHODS The paradigm used was a classical double-step target to elicit the shortening of saccade gains in response to a 2° backward step (20% of target eccentricity). Two conditions were run in the pre- and postadaptation phases wi...
متن کاملThe effect of distractors on saccades and adaptation of saccades in strabismus
This paper reports two experiments to determine the contribution of the suppressing eye to the generation of saccadic eye movements in constant strabismus. Eye movements were recorded using a Skalar infra-red recorder. Experiment 1 tested six participants with constant strabismus, pathological suppression and no clinically demonstrable binocular single vision (BSV). We explored the effect of vi...
متن کاملTransfer of adaptation from visually guided saccades to averaging saccades elicited by double visual targets.
The adaptive mechanisms that control the amplitude of visually guided saccades (VGS) are only partially elucidated. In this study, we investigated, in six human subjects, the transfer of VGS adaptation to averaging saccades elicited by the simultaneous presentation of two visual targets. The generation of averaging saccades requires the transformation of two representations encoding the desired...
متن کاملAdaptation of voluntary saccades, but not of reactive saccades, transfers to hand pointing movements.
Studying the transfer of visuomotor adaptation from a given effector (e.g., the eye) to another (e.g., the hand) allows us to question whether sensorimotor processes influenced by adaptation are common to both effector control systems and thus to address the level where adaptation takes place. Previous studies have shown only very weak transfer of the amplitude adaptation of reactive saccades--...
متن کاملDisconjugate adaptation of saccades: contribution of binocular and monocular mechanisms
We studied the effects of prism-induced disparity on static and intrasaccadic alignment in six normal human subjects. A ten diopter base-out prism, calling for convergence, was placed in front of the central field of the right eye, so that at the center the eye viewed through the prism; at left and right, outside the prism. During 15 min of training, subjects made repetitive saccades solely in ...
