Midnight Blue—A new system for color vision

The swirling skies of Vincent Van Gogh's Starry Night illustrate a mystery that has eluded biologists for more than a century—why do we perceive the color blue in the dimly lit night sky? A newly discovered mechanism of ...

Eye's recycling process key to seeing color, bright light

As many of us learned in high school science class, the retina's rods and cones allow us to see. Rods are for night vision, and cones operate in bright light and allow us to distinguish colors. But although scientists have ...

How the retina marches to the beat of its own drum

Researchers at Johns Hopkins and the University of Washington report new research that sheds light on how the retina sets its own biological rhythm using a novel light-sensitive pigment, called neuropsin, found in nerve cells ...

Neuroscience

Shapes, lines and movements are in the eye of the beholder

New thinking about how we perceive shapes, lines and movement suggests this information is first deciphered in the retina of the eye, rather than within the brain's visual cortex as previously thought.

Genetics

New color blindness cause identified

A rare eye disorder marked by color blindness, light sensitivity, and other vision problems can result from a newly discovered gene mutation identified by an international research team, including scientists from Columbia ...

New function for rods in daylight

(Medical Xpress)—Vision – so crucial to human health and well-being – depends on job-sharing by just a few cell types, the rod cells and cone cells, in our retina. Botond Roska and his group have identified a novel ...

Neuroscience

Inducing visual function

Scientists from the groups of Botond Roska and Witold Filipowicz at the Friedrich Miescher Institute for Biomedical Research have resolved the mechanism controlling the maintenance of the light sensitive "antennas" of photoreceptors ...
