A retinal ganglion cell (RGC) is a type of neuron located in the retina of the eye. These cells receive visual information from photoreceptors, such as rods and cones, and transmit it to the brain via their axons, which form the optic nerve. RGCs play a crucial role in processing visual signals, including aspects like brightness, color, and motion. There are different types of retinal ganglion cells, each specialized for various functions in vision. For example, some RGCs are responsible for detecting light intensity, while others are involved in color perception. The proper functioning of retinal ganglion cells is essential for clear vision and overall visual processing.
