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 ...

The pupillary reflex is a dynamic adjustment of the iris that regulates retinal illumination in response to changes in ambient light. This process relies on an afferent limb, whereby photoreceptors in ...

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 ...

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.

The creation of a bionic eye that mimics the widening and shrinking of the pupil may bring us one step closer towards helping people with certain visual impairments. Light enters the eye via the pupil ...

Picture this, if you will: Aphantasia can be detected with an eye-opening look into our pupils. To first gauge the pupillary reflex of non-aphantasic people, the researchers sought 42 study ...
