Light sensitive cells in the fetal retina communicate as part of an interconnected network, giving the retina more light sensitivity during development that previously believed.
Study challenges the widely accepted belief that all light information is relayed through the suprachiasmatic nucleus, which synchronizes the circadian rhythm.
In lower mammals, the iris may sense light and cause the pupils to constrict without involving the brain, a new study reports.
Researchers have made novel discoveries about how the eye processes light on both cellular and molecular levels.
Mice without rods and cones were able to use ipRGCs to detect light and possibly form low acuity images.
