SPOKANE, Wash.—Measuring how the eyes’ pupils change in response to light—known as the pupillary light reflex—could potentially be used to screen for autism in young children, according to a study ...

The human retina contains some 100 million photoreceptor cells. When these are stimulated with light, they communicate that information to the brain and we perceive light. Researchers have now ...

Pupil size in response to light could serve as a biomarker for concussion, according to a study published in Life. “A concussive injury to the brain is associated with changes in the PLR [pupillary ...

New research points to an easily measured eye response to light as a potentially useful way of diagnosing autism in very young children. Further testing is currently underway in a large cohort of ...

Objective Pupillary light reflex (PLR) metrics are enhanced in adolescents with concussion. It is not known if these PLR metrics in concussed adolescents return back to the normal range at recovery.

May 28, 2010 (Philadelphia, Pennsylvania) — In an effort to find discrete phenotypic features that are consistently present in autistic populations, researchers at the University of Missouri Thompson ...

WEST LAFAYETTE, Ind. – Capturing objective data in about five seconds that can aid concussion diagnoses through an iPhone, the Reflex PLR Analyzer, an industry-disruptive diagnostic tool for traumatic ...

A blue glare illusion was perceived to be brightest and caused larger pupil constriction The Department of Computer Science and Engineering at Toyohashi University of Technology formed a research team ...

An artificial vision sensor inspired by the human pupil adapts automatically to light, maintaining clear perception from darkness to glare and sharply improving recognition accuracy in machine ...

Researchers measured people's perceived brightness and pupillary response after viewing glare illusions presented in a variety of different colors. A glare illusion is an optical illusion that has a ...
