  • Becker W, Fuchs AF (1985) Prediction in the oculomotor system: smooth pursuit during transient disappearance of a visual target. (springer.com)
  • Finally, we show that the ability to adjust acceleration duration during pursuit resilience depends on the integrity of the oculomotor vermis (OMV) as indicated by the complete loss of the duration adjustment following a surgical lesion of the OMV in one rhesus monkey we could study. (frontiersin.org)
  • visually
  • Both the mean and variation of the visually driven pursuit response can be accounted for by the combination of the mean tuning curves and the correlated noise within the sensory representation of visual motion in extrastriate visual area MT. Sensory-motor and motor circuits have both housekeeping and modulatory functions, implemented in the cerebellum and the smooth eye movement region of the frontal eye fields. (nih.gov)
  • retinal
  • These results suggest that the weighting of retinal and extraretinal signals is dynamically modulated during the different phases of pursuit. (arvojournals.org)
  • Experiment
  • We conducted two experiments to probe these interactions by briefly (200 and 400 ms) blanking the moving target (45° or 135° tilted bar) during steady state (Experiment 1) and at different moments during the early phase of pursuit (Experiment 2). (arvojournals.org)
  • exhibits
  • Finally, pursuit exhibits a number of voluntary characteristics that happen on short timescales. (nih.gov)
  • acceleration
  • However, this drop in acceleration gets compensated by an increase in the duration of the acceleration profile, thereby keeping initial pursuit gain constant. (frontiersin.org)
  • dynamics
  • This is the first instance of a model integrating all aspects of pursuit dynamics within one coherent and simple model and without switching between different parallel mechanisms. (weebly.com)
  • motor
  • Motor plasticity or motor learning, recently demonstrated for pursuit, is also incorporated and simulated. (springer.com)
  • These features make pursuit an excellent exemplar for understanding the general properties of sensory-motor processing in the brain. (nih.gov)
  • suggests
  • Our model suggests that the brain circuitry generating a pursuit command might be simpler than previously believed and only implement the functional equivalents of two Kalman filters whose outputs are optimally combined. (weebly.com)
  • show
  • It was noticed that the offset of pursuit did not show the ringing seen in the onset so this was quantified in one subject. (springer.com)
