Gamma-Movement and the Pupillary Reflex
The American Journal of Psychology, 1965Bartley distinguished six different kinds of gamma-movement and attributed all of them to a spatio-temporal distribution of the retinal image resulting from differences in reaction-time of rods and cones and differences in intensity of stimulation from the center toward the periphery of the retina.1 He purported to discredit earlier theories which ...

Characteristics of a Brisk or Sluggish Pupillary Light Reflex: A Nursing Perspective
Journal of Neuroscience Nursing, 2020Supplemental digital content is available in the text. ABSTRACT BACKGROUND Pupillary light reflex (PLR) has traditionally been assessed using a pen torch (light). Although the terms “brisk” or “sluggish” are often used, it is unclear what characteristics

Automatic Detection of Driver Impairment Based on Pupillary Light Reflex
IEEE transactions on intelligent transportation systems (Print), 2019The main objective of this paper is to determine the feasibility of designing a driver drunkenness detection system based on the dynamic analysis of a subject’s pupillary light reflex (PLR).

Effects of pupillary light and darkness reflex on the generation of pro‐ And anti‐saccades
European Journal of Neuroscience, 2020Saccades are often directed toward a stimulus that provides useful information for observers to navigate the visual world. The quality of visual signals of a stimulus is influenced by global luminance, and the pupil constricts or dilates after a ...

Visual evoked responses and pupillary reflex have been recorded simultaneously with the automatic perimeter PERIMATIC. Results are reported from normal patients and several cases of visual pathway disturbances. These results are compared to the subjective responses obtained with the same instrument.

The pupillary light reflex pathway
Neuro-Ophthalmology, 1997Since Wernicke1 publicized the matter in the 1880s, it has been considered practically a ‘law of nature’ that the pupillary light reflex pathway is a simple brainstem reflex.

Saccadic suppression of the pupillary light reflex
Experimental Neurology, 1966Abstract The visual threshold is known to be elevated by as much as one or two log units just before and during both voluntary and involuntary saccadic eye movements (saccadic suppression). Experiments were carried out to discover whether or not the direct pupillary reflex is suppressed in association with saccadic suppression.

Pupillary Light Reflex Variability as a Predictor of Clinical Outcomes in Subarachnoid Hemorrhage
Journal of Neuroscience Nursing, 2019Supplemental digital content is available in the text. ABSTRACT BACKGROUND: A change in the pupillary light reflex (PLR) is a sensitive indicator for detecting expanding intracranial lesions.

Pupillary light reflex in borderline diabetes mellitus
Diabetes Research and Clinical Practice, 1989It is well known that in diabetes mellitus the early phase insulin release response to glucose becomes blunted. Besides, autonomic neuropathy develops frequently. The autonomic nerve function is related to insulin release in normal subjects. Therefore, in the present study the autonomic function was investigated in different degrees of the early phase ...
