 Context examples 

However, these ganglion cells responded to green light even where green cone cells were absent.

(New color vision pathway unveiled, NIH)

In the back of the eye, there is a site called the fovea which contains cone cells, of three kinds responding either to red, green, or blue light.

(Arrangement of light receptors in the eye may cause dyslexia, Wikinews)

This protein plays a role in the phosphorylation of opsins which modulates the photoresponsiveness of cone cells.

(G Protein-Coupled Receptor Kinase 7, NCI Thesaurus)

An autosomal recessive genetic disorder affecting the cone cells of the eye.

(Achromatopsia, NCI Thesaurus)

Rod cells activate horizontal cells, which inhibit cone cell signaling to retinal ganglion cells.

(New color vision pathway unveiled, NIH)

In one patch within the fovea, there are cone cells for red and green but none for blue.

(Arrangement of light receptors in the eye may cause dyslexia, Wikinews)

Thus, the ganglion cells can integrate both green light information coming from rod cells and blue/UV light information coming from cone cells in order to send information about color to the brain.

(New color vision pathway unveiled, NIH)

The researchers surveyed retinal ganglion cells, which integrate signals from cone cells and transmit information about color to the brain, by measuring their responses to different colored lights.

(New color vision pathway unveiled, NIH)

Because of their locations, the cone cell signals can’t be compared in the same way as they are in people to determine color.

(New color vision pathway unveiled, NIH)

Most other mammals only have 2 types of cone cells, for green and blue/ultraviolet (UV) light.
