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 ...

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 ...

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 ...
