| 41. | Gradually, the unwanted substance makes its way into the pigment epithelium, a layer of cells underlying the rods and cones.
|
| 42. | Some, without rods and cones, could set their biological clocks perfectly well in response to daily changes in light levels.
|
| 43. | Scientists have known since the 1850s that the specialized cells found in the eyes called rods and cones are sensitive to light.
|
| 44. | The workers had tracked down patients with rare diseases wiping out classic rod and cone photoreceptor function but preserving ganglion cell function.
|
| 45. | Under naturalistic lighting conditions, responses to the rods and cones are superimposed on the melanopsin response of giant retinal ganglion cells.
|
| 46. | There is another possibility : Most people know that the eye has 2 kinds of light sensor-the rods and cones.
|
| 47. | Aging also affects light-sensing cells called rods and cones in the retina, the tissue in the back of the eye.
|
| 48. | RP is actually a group of diseases that gradually destroy the eye's light-sensing cells, called rods and cones.
|
| 49. | The work was done using patients with rare diseases that wiped out classic rod and cone photoreceptor function but preserved ganglion cell function.
|
| 50. | The pigmented retina is formed by rods and cones and composed of small cilia typical of the ependymal epithelium of the neural tube.
