An animal’s ability to perceive light incorporates many complex processes. Now, researchers in Craig Montell’s lab at UC Santa Barbara have used fruit flies and mice to make novel discoveries about sensory physiology at both cellular and molecular levels that are important for light processing. Their most recent findings improve the scientific understanding of the… Read more

The cornea is a light-sensitive tissue, according to new research from the University of Washington. The findings add to past work proving the retina senses light as part of its role in synchronizing our body clocks to Earth’s cycle of light and darkness. Ophthalmologist Russell Van Gelder says: “Many interesting testable hypotheses follow from this… Read more

Optogenetics has taken neuroscience by storm in recent years because the technique allows scientists to study the brain conveniently in animals, activating or inhibiting selected groups of neurons at the flip of a switch. Most often, scientists use a fiber optic cable to deliver light into the brain. Researchers at Emory and Georgia Tech have… Read more

The octopus can change the color, pattern, and even texture of its skin not only for purposes of camouflage but also as a means of communication. The most intelligent, most mobile, and largest of all mollusks, these cephalopods use their almost humanlike eyes to send signals to pigmented organs in their skin called chromatophores, which… Read more
