Latest Photosensitive ganglion cell Stories
People working the graveyard shift may want to literally see red because according to a new study -- the color of light animals are exposed to at night can affect mood regulation.
Among the animals that are appealing “cover models” for scientific journals, lancelets don’t spring readily to mind.
A new research report published in The FASEB Journal (https://www.fasebj.org) will help ophthalmologists and scientists better understand a rare genetic disease that causes increased susceptibility to blue light, night blindness, and decreased vision called Enhanced S-Cone Syndrome or Goldman-Favre Syndrome.
Creatures are not born hardwired to see.
Retinitis pigmentosa affects over one million people worldwide and is manifested by a progressive loss of sight, eventually leading to blindness.
Like a wristwatch that needs to be wound daily for accurate time-telling, the human circadian system â€” the biological cycles that repeat approximately every 24 hours â€” requires daily light exposure to the eyeâ€™s retina to remain synchronized with the solar day. In a new study published in the June issue of Neuroscience Letters, researchers have demonstrated that when it comes to the circadian system, not all light exposure is created equal.
Researchers have discovered that a set of light-responsive retinal cells that form connections to the circadian clock are functional very early in development, from the day of birth. Although the cells are sensitive to light, they do not participate in image formation, a process that matures later on.
