Fovea y retina
WebA retinal ganglion cell ( RGC) is a type of neuron located near the inner surface (the ganglion cell layer) of the retina of the eye. It receives visual information from photoreceptors via two intermediate neuron types: … WebHowever, at the fovea, the ganglion cells and the bipolar neurons radiate away from the cones in the fovea. Think of the crown of your head. All of the hairs radiate out from this point exposing the scalp. Because of this arrangement light striking the fovea has direct access to the photoreceptors, enhancing vision in this region of the retina.
