In mammals, photoreceptors located in the inner retina convey photic information to the brain, regulating diverse non-image-forming tasks such as pupillary light reflexes and photic synchronization (entrainment) of daily activity rhythms. In nonmammalian vertebrates, the retina, deep brain photorece

Relationships between increased adiposity and fat-soluble vitamin storage and metabolism are poorly understood. To examine these associations, 6% or 21% dietary fat was fed to rats for 11 weeks and tissue vitamin A storage determined. Two levels of supplemental vitamin A were administered. At the en
