  • nystagmus
  • And although all the papers say you can perform the test in the presence of spontaneous nystagmus, a non-expert (like me) has a lot of trouble distinguishing nystagmus from a catch-up saccade when the patient's eyes are bopping around like crazy. (emcrit.org)
  • saccadic
  • First, its strong response to saccades may function as a saccadic suppressor (via one of its target neurons) for cells involved in figure-ground discrimination. (jneurosci.org)
  • The thorax and head perform a series of saccadic changes in yaw, with a quite stable orientation of the head between saccades ( van Hateren and Schilstra, 1999 ). (jneurosci.org)
  • 10 It is based on four parameters: ability (how long the child stays with the task), accuracy (saccadic intrusions, refixations for pursuits and by over- or undershoots for saccades), head movement and body movement (ability to control motor overflow). (reviewofoptometry.com)
  • responses
  • The responses to the two modified stimuli are strongly different from the response to the original stimulus, showing the importance of translation and saccades for the H1 response to natural optic flow. (jneurosci.org)
  • patients
  • In case of bilateral vestibular hypofunction, patients use saccades to compensate for the reduced vestibulo-ocular reflex function, with covert saccades occurring even during the head displacement. (readbyqxmd.com)
  • targets
  • A close timing relationship between saccade onset to fixate a stepping target and swing phase initiation of the targeting limb has been demonstrated in young individuals stepping on illuminated targets (Hollands et al. (springer.com)
  • 10 With saccades, use two different targets and have the patient alternate viewing between each one only when instructed to do so. (reviewofoptometry.com)
  • head
  • and (2) a stimulus in which the saccades were removed by assuming that the head follows the smooth flight trajectory (this stimulus produced alternating zero or nearly saturating spike rates). (jneurosci.org)
  • object
  • Second, its intersaccadic response may increase the signal-to-noise ratio (SNR) of wide-field neurons involved in detecting translational optic flow between saccades, in particular when flying speeds are low or when object distances are large. (jneurosci.org)
