Explanatory panel on what the retina is.
The retina is the part of the eye responsible for vision and is part of the central nervous system. It is made up of layers of neurons specialized in transforming light into signals that are sent to the brain through the optic nerve.
In the retina, there are several cell types specialized in different functions. The textured panels show the location of the photoreceptors responsible for capturing light. Melanopsin cells are responsible for informing the brain of the light intensity, whether it is day or night. Ganglion cells conduct messages from the eye to the brain; and Müller cells protect all other neurons in the retina and facilitate their survival.
