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 ...

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 ...

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 ...

New findings from researchers at UCLA Health suggest that measuring changes in how pupils react to light could help predict recovery from depression and personalize transcranial magnetic stimulation ...

The horizontal axis represents the time elapsed following the presentation of the image, while the vertical axis denotes the degree of change in pupil diameter relative to the image presentation. A ...

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 ...
