Latest Photoreceptor cells Stories
Biologists have uncovered a key regulatory mechanism used for gene expression in the visual system.
In this month's Physics World, Richard Taylor, professor of physics, psychology and art at the University of Oregon, warns that artificial retinal implants â€“ a technology fast becoming a reality â€“ must adapt to the unique features of the human eye in order to become an effective treatment.
Turns out our sensitivity to seeing in color is not only due to cone cells in the retina, but also through the thyroid gland by controlling which visual pigment is produced in the cones.
Melanopsin, a light sensor that sets the circadian rhythm- the bodyâ€™s biological clock- also plays an important role in vision, according to this study.
Retinitis pigmentosa affects over one million people worldwide and is manifested by a progressive loss of sight, eventually leading to blindness.
Veterinary vision scientists at the University of Pennsylvania have safely and successfully used a viral vector in targeting a class of photoreceptors of the retina called rods, a critical first step in developing gene therapies for inherited blindness caused by rod degeneration.
Research by Johns Hopkins sensory biologists studying fruit flies, has revealed a critical step in fly vision.
Researchers at Washington University School of Medicine in St Louis have peered deep into the eye of the chicken and found a masterpiece of biological design.
The eyes of nocturnal bats possess two spectral cone photoreceptor types for daylight and colour vision. Reporting in the open-access, peer-reviewed journal PLoS ONE
Researchers from the John Hopkins School of Medicine have discovered a new type of cell used for vision in fish.
