Researchers are reporting progress in understanding whether a second light-sensing pathway in mammals indeed contributes to the detection of ambient light for controlling body functions. January 10, ...
The eye's light-sensing retina taps different circuits depending on whether it is generating image-forming vision or carrying out a non-vision function such as regulating pupil size or sleep/wake ...
The study, led by researchers from UNSW Sydney and published in eLife, found that the pupils of people with aphantasia did not respond when asked to imagine dark and light objects, while those without ...
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 ...

Medically reviewed by Johnstone M. Kim, MD Key Takeaways The pupil controls how much light enters the eye, allowing for clear ...
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 ...
Pupillometry, the precise measurement of pupil size and dynamics, has emerged as a valuable tool in evaluating both autonomic nervous system integrity and central neural function. In particular, ...
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 ...
