The route of visual information from the visual receptors (rods and cones) to the brain goes from receptors to the bipolar cells to the ganglion cells through the optic nerve and finally to the brain. Describe in greater detail the route from the bipolar cells to the brain, specifically defining the ganglion cells and optic nerve.

The bipolar cells make contact with the ganglion cellswhich are neurons that receive their input from the bipolar cells. The axons from the ganglion cells join to form the optic nerve, which turns around and exits the eye. Half of each optic nerve crosses to the opposite side of the brain at the optic chiasm. Axons from the optic nerve then separate and go to several locations in the brain. In humans, most go to the thalamus, which then sends information to the primary visual cortex in the occipital lobe.
