Circadian biology: the physiology of inner retinal photoreceptors.
Non-traditional photoreceptors detect overall irradiance in the vertebrate retina. Such cells in the mouse inner retina show increased intracellular Ca(2+) levels following illumination. Neurons in the outer retina of fish also display characteristics appropriate for an irradiance detector.
