The neuronal pathway subserving the pupillary light reflex
Brain Research, 1978The pupillary light reflex was investigated using electrical stimulation along the pathway and recording in the short ciliary nerves. The discharge of single units in the ciliary ganglion was compared during diffuse light stimuli and electrical stimuli.

Critical Duration for the Pupillary Light Reflex*
Journal of the Optical Society of America, 1969Light reflexes of the eye pupil are measured with an infrared scanning pupillometer in response to a 74-deg field. At threshold, the pupillary system responds to stimulus energy for short flashes and stimulus magnitude for long flashes. On a plot of log-flash magnitude vs log-flash duration, the intersection of the constant-energy asymptote and the ...

The pupillary light reflex pathway
Neurology, 2008The anatomy of the human pupillary light reflex (PLR) pathway is a matter of debate. The aim of this study was twofold: namely, to investigate the association of a relative afferent pupillary defect (RAPD) in acquired suprageniculate lesions with the location and extent of the cerebral lesions.

Pupillary light reflex in panic disorder
European Archives of Psychiatry and Clinical Neurosciences, 2004Although many previous studies reported abnormalities of autonomic function in patients with panic disorder (PD), almost all targets in those studies primarily focused on cardiovascular autonomic functions. In the present study, we determined whether PD patients exhibited abnormalities in the pupillary autonomic nervous system (ANS).Before and after ...

Smartphone-based pupillary light reflex test system
2013 13th International Conference on Control, Automation and Systems (ICCAS 2013), 2013The pupillary light reflex (PLR) test is the method of examining the immediate reaction of the pupil by light stimuli, and dysfunctions in autonomic nervous system can be evaluated quickly and easily through this method. Existing pupillary light reflex examinations utilize medical penlights to provide light stimuli at the pupil of the examined person ...
