Multisensory integration has been recently shown to produce a larger pupil size than unisensory constituents. Superior colliculus (SC), an important laminar nucleus in the midbrain, not only engages ...

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 ...

A pilot study found that children with autism show a significantly stronger pupillary constriction to light than typically ...

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 ...

Accurate estimation of pupillary light reflex (PLR) latency is important in clinical and research settings, yet reported results are often difficult to compare due to ...

This educational video explores the fascinating mechanisms of the pupillary light reflex, explaining how neural pathways control pupil constriction in response to illumination to protect the retina ...
