It has recently become apparent that cone and rod photoreceptors undergo several distinct phases of development 126,127, and the following scenario has been established in the ferret retina.

Can cats see in the dark? We have done the research. Jump in to read all about cat's vision and how they can see in the dark!

There are two types of photoreceptors: rods, which are sensitive to light and dark, and cones, which are sensitive to color. Cones are further divided into three types, each responding to a ...

In wild-type, retinal ganglion cell layer (GCL), inner nuclear layer (INL), inner plexiform layer (IPL), and nuclear layers of rod and cone photoreceptors are distinct, and rod outer segment (OS ...

Cells in the tapetum act like a mirror, reflecting light that passes between the rods and the cones back to the photoreceptors and giving them another chance to pick up the small amount of light ...

Within rods and cone photoreceptors, a small soluble molecule called cGMP links photon absorption to the electrical activity of the photoreceptor. In the light, cGMP is destroyed and ion channels ...
