5 Brown faculty elected to world's largest scientific body

... Specifically, he explores structural and functional diversity among the ganglion cells of the eye, the retinal neurons that communicate directly with the brain. Current research focuses on one very unusual type of ganglion cell that senses light directly. These neurons drive reflexive responses ...

Blind humans lacking rods and cones retain normal responses to non-visual effects of light

... mammals have an additional light-sensitive photoreceptor in the retinal ganglion cell layer (pRGCs) that is directly sensitive to light and is primarily ... effects were maximal in response to wavelengths of light that the retinal ganglion cells respond best to, and not the wavelength that the visual system ...

Growth factor TGF-B helps maintain health of retinal blood vessels

... tissue, and fluid was leaking out of the vessels, which does not happen when the vessels are functioning properly. These defects led to the death of ganglion cells (nerve cells in the innermost part of the retina) and a loss of visual function. According to D'Amore and Walshe, the demonstration of the ...

Experts examine causes, treatment and prevention of glaucoma

... Although scientists know progressive degeneration of retinal ganglion cells and their axons is the primary cause of glaucoma, researchers have yet to identify a way to stop or prevent the degeneration. The challenge ...
