  • duration
  • The three test parameters (total mean duration, total mean error duration, and coordination difficulty) of the test were treated as dependent variables while sex and age (separated into 5-year age groups) were the independent variables. (edu.pl)
  • The duration of single saccades depends on age to a lesser degree and does not change in patients with Parkinson's disease. (springer.com)
  • suppression
  • The frontal eye field (FEF) is known to play also an important role in the control of saccades and in their suppression ( Leigh and Zee, 2006 ). (frontiersin.org)
  • A program of Vision Therapy may reduce the frequency of patching since the goal of amblyopia therapy is to improve eye coordination, improve stereopsis (depth perception) and reduce suppression. (covd.org)
  • compensatory
  • The scatter of compensatory saccades (as measured by the PR score) may be a surrogate early marker of clinical recovery, given its relationship to the Dizziness Handicap Inventory. (frontiersin.org)
  • subjects
  • Subjects performed an event-related delayed movement task requiring that a reach or saccade be planned and executed toward one of two spatial target positions. (jneurosci.org)
  • All subjects had abnormal gains across one or more stimulus conditions (horizontal smooth pursuit, saccades, or OKN). (arvojournals.org)
  • We wondered whether this natural variability would also be present in the motor commands that initiated saccades of cerebellar patients, and if so, whether these subjects would show a reduced ability to compensate for that variability. (jneurosci.org)
  • Subjects made saccades by following a target light. (jneurosci.org)
  • According to the data obtained, the saccade characteristics depend on the age in both the subjects without neurological symptoms and parkinsonian patients. (springer.com)
  • hand coordination
  • Overall, our results imply that the output of M1 has limited contribution in driving the eye motion during our eye-hand coordination task. (jneurosci.org)
  • The goal of the present study was to investigate the contribution of the primary motor cortex (M1) into eye-hand coordination. (jneurosci.org)
  • This use of a common spatial target representation can facilitate the first stages of the coordinate transformations required to convert sensory inputs (e.g., visual) into motor (e.g., limb) outputs and assist eye-hand coordination ( Andersen and Buneo, 2002 ). (jneurosci.org)
  • Purpose The aim of the present pilot study was to assess sex and age differences in sensory-motor coordination by examining eye-hand coordination in an elderly population. (edu.pl)
  • The values of all the parameters measuring eye-hand coordination showed a gradual deterioration with age. (edu.pl)
  • The pilot study warrants additional data collection, where large-scale quantitative research may help in the development of suitable prevention strategies to slow the impact of aging on eye-hand coordination abilities in the elderly. (edu.pl)

  • Research review of eye-hand coordination, walking, driving, and reading skills of children and adults with amblyopia. (covd.org)
  • rotations
  • Gaze displacement and inter-segmental coordination during large whole body voluntary rotations. (springer.com)
  • Our study fills an important gap in our understanding of eye-head coordination by combining these two approaches to compare gaze trajectories with and without whole-body rotations during saccades that are made when the head and body are fixed with respect to the chair. (jneurosci.org)
  • control
  • In the current study, we incorporate recent experimental findings into a new model for three-dimensional (3-D) gaze control, verify our mathematical approach with the use of simulations, and then use the model to explore some poorly understood aspects of eye-head coordination. (frontiersin.org)
  • We investigated the effects of monocularity on oculomotor control by examining the characteristics of the horizontal saccades of people with one eye, and comparing them to those of a group of age-matched controls who viewed the stimuli monocularly and binocularly. (arvojournals.org)
  • mechanisms
  • This finding is most likely related to the fact that learning mechanisms responsible for saccade yoking develop during childhood until adolescence. (nih.gov)
  • interactions
  • In particular, we explore the interactions between the spatiotemporal rules of eye-head coordination, the 3-D constraints on eye/head orientation, and the resulting orientations of the eye (and thus retina) in space. (frontiersin.org)
  • These interactions are crucial both for understanding gaze motor coordination, and for understanding its visual consequences. (frontiersin.org)
  • Differential auditory-oculomotor interactions in patients with right vs. left sided subjective tinnitus: a saccade study. (cnrs.fr)
  • motor
  • The Pupil Reflects Motor Preparation for Saccades - Even before the Eye Starts to Move. (cnrs.fr)
  • Yet, the binocular motor coordination is not perfect. (frontiersin.org)
  • This ability to correct for variability in the motor commands that initiated a saccade was a predictor of each subject's ability to learn from endpoint errors. (jneurosci.org)
  • Therefore, the cerebellum corrects for variability in the motor commands that initiate saccades within the same movement via an adaptive response that not only exhibits strong sensitivity to previous endpoint errors, but also rapid forgetting. (jneurosci.org)
  • A computational framework that captures these ideas is one in which motor commands are monitored via a forward model, predicting sensory consequences and allowing for within-saccade compensation. (jneurosci.org)
  • voluntary
  • Different effects of double-pulse TMS of the posterior parietal cortex on reflexive and voluntary saccades. (cnrs.fr)
  • generator
  • Internal transformations decomposed the 2-D gaze command into 3-D eye and head commands with the use of three coordinated circuits: (1) a saccade generator, (2) a head rotation generator, (3) a VOR predictor. (frontiersin.org)
  • study
  • This study characterized gaze holding and gains for smooth pursuit, saccades, and optokinetic nystagmus (OKN) in DS children with infantile nystagmus (IN). (arvojournals.org)
  • organization
  • We assessed the age, sex, tumor size, degree of canalicular weakness, and preoperative video head impulse test (gain and saccade organization measured with PR score). (frontiersin.org)
  • Gain and saccade organization were compared with postoperative values at discharge and also at 1, 3, and 6 months. (frontiersin.org)
