A new study showed that NeurOptics Pupillometers reliably measure the presence and quality of the pupillary light reflex after cardiac arrest and during resuscitation, producing readings that ...

The eye's pupils constrict (shrink) in brightness and dilate (expand) in darkness. The pupillary light response was historically considered a low-level reflex without any cognitive component. Here, we ...

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 ...

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 ...

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 ...

Generally, a doctor shines a bright light into an unconscious patient''s eye to check for brain death. The brain is alright if the pupil constricts because in mammals, the brain controls the pupil. Or ...

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 ...

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 ...

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 ...
