The rod cells can also be affected by this.

In the dark, a small light stimulus will be enhanced by the different photoreceptors (rod cells).

The new snapshot should help researchers figure out how rod cells respond to light.

Peripheral vision is good at detecting motion (a feature of rod cells).

The rod cells, which play an important role in night vision, are damaged early in the course of the disease.

On average, there are approximately 125 million rod cells in the human retina.

Cone cells are less sensitive to light that rod cells.

Their reaction to stimuli is faster than that of the rod cells.

Because light is so scarce, fish often have larger than normal, tubular eyes with only rod cells.

Green fluorescent signs can be seen better in dark conditions than other colors, as the human rod cell is more sensitive to these wavelengths.
