One of the first things that most designers forget about CSS descendant selectors is that they are flexible. When CSS defines a descendant, it doesn't care whether the tag in question is the direct child, the grandchild, or some great-great-great-descendant of the initial element.
From the retina, visual information passes onto the bipolar cells and then to the optic nerve's ganglion cells. The optic nerve, which begins at the retina, is the sole visual pathway to the brain. Light information is conveyed as an electrical action potential through the neurons.
The information from the eye is carried by the axons of the retinal ganglion cells (the 3Â° visual afferent) to the midbrain and diencephalon. This chapter will provide more information about visual pathway organization and the visual processing that occurs within the brain.he inferior surface of the brain illustrating the visual pathway. The termination sites of the retinal ganglion cell axons in three nuclei that are not considered a part of the visual pathway are also illustrated.
