• diameter
  • We demonstrated that this PIPR was not correlated with subject characteristics such as age , race and gender , and that the only factor affecting the magnitude of the PIPR was the baseline pupil diameter . (uab.edu)
  • fibers
  • The sparing of the pupil is thought to be associated with the microfasciculation of the edge fibers which control the pupillomotor fibers, which control the pupil. (wikipedia.org)
  • pretectal
  • Nerves involved in the resizing of the pupil connect to the pretectal nucleus of the high midbrain, bypassing the lateral geniculate nucleus and the primary visual cortex. (wikipedia.org)
  • responses
  • Measuring humans' pupil responses has the potential to improve human-computer interaction and adaptive decision support systems. (wikipedia.org)
  • They contribute to the regulation of pupil size and other behavioral responses to ambient lighting conditions. (wikipedia.org)
  • light
  • These ipRGCs contribute to the PLR and are responsible for the sustained pupilloconstriction observed following light offset (the post-illumination pupil response (PIPR)) . (uab.edu)
  • Using a newly-developed , wide-field optical system , we demonstrate that all normal subjects display a post-illumination pupil response in response to a 10-second , 470nm light stimulus . (uab.edu)
  • ganglion
  • Signals from photosensitive ganglion cells have multiple functions including acute suppression of the hormone melatonin, entrainment of the body's circadian rhythms and regulation of the size of the pupil. (wikipedia.org)
  • eyes
  • In a report in the June 19 issue of the journal Current Biology , Neuroscience Professor King-Wai Yau and colleagues detail how the pupils in a mouse's eyes get smaller when the animal is moved from a dark to a lit room even when the nerve connections between the animal's brain and eyes are severed.

  • response
  • In conclusion , using a newly-developed , wide-field optical system , we have demonstrated that all normal subjects display a post-illumination pupil response which is reduced in patients with GON . (uab.edu)
