University of Tokyo researchers have found that the light reflex of the pupil is modulated by light stimulation inside the blind spot in normal human observers, even though that light is not perceived ...

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 ...

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 ...

Neurological Pupil index Neurological Pupil index scores (NPI-Diff) may be an effective early quantitative measure to indicate neurologic decline even in patients in neurocritical care units with ...

In medicine, the pupillary reflex or pupillary light reflex, is the reduction of pupil size in response to light. It is a normal response and dependent on the function of the optic nerves and ...

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 ...

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 ...
