Researchers uncover how specific retinal cells respond to the artificial light generated by cell phone and tablets. The study reveals how retinal ganglion cells process ambient light and reset our circadian clocks, leading to sleep disruptions.
Study revels M1 ganglion cell photoreceptors can tune into different ranges of light intensity.
In lower mammals, the iris may sense light and cause the pupils to constrict without involving the brain, a new study reports.
A new study reveals the color of light can have an impact on whether we're sleepy or fully aroused.
A new study reports high contrast visual stimulation can help damaged retinal neurons to regrow optic nerve fibers.
Researchers report green light can help to promote sleep, while blue lights can delay the need to rest, at least in mice.
Researchers report axon regeneration can be boosted by using optogenetics or chemogenetics to enhance neural activity.
A new study sheds light on how the retina sets its own biological rhythm using a novel light-sensitive pigment called neuropsin.
Melanopsin and S-cones battle for control of the pupil under blue light.
Using computer models, researchers discover melanopsin pigment in the eye is more sensitive to light than rhodopsin pigment.
New research concludes the eye, which depends on light to see, also needs light to develop normally during pregnancy.
