The retina is home to two different kinds of light receptor cells—rods and cones. (Both are named after their relative shapes.) Cones work in bright light and register detail, while rods work in ...

A literature search revealed that the relaxation of blood vessels in response to light, called photorelaxation, had been described almost 50 years earlier, but the underlying mechanisms had never been ...

Scientists are aiming to determine the composition and topology of physiological Ashwell-Morell receptor ligands. Their findings will help uncover the receptor's still-hidden secrets.

Different receptors are sensitive to different stimuli (eg receptors in the eye are sensitive to light). A nerve cell/neurone carries information in the form of nerve impulses from the receptor to ...
