Pons Region of brain stem between the midbrain and medulla oblongata; serves as the bridge (connection) between the two regions, and the cerebellum. Some neurons make connections at incredibly long distances, sending their axons all the way across the brain, and those long-distance connections aren't represented fully in this dataset. The choroid is a layer in the eye's membrane that contains the blood vessels. The brain development process actually uses visual information entering from outside to become more precisely organized than it could with intrinsic molecular mechanisms alone. It controls eye movement, constantly telling our eye muscles to move toward the correct stimulus of light (the object we want to look at). . Please note that the limbic lobe is functional . When light hits its corresponding rod or cone, the cell activates, firing a nerve impulse through the optic nerve — the middle man between the eye and the brain. The visual system comprises the sensory organ (the eye) and parts of the central nervous system (the retina containing photoreceptor cells, the optic nerve, the optic tract and the visual cortex) which gives organisms the sense of sight (the ability to detect and process visible light) as well as enabling the formation of several non-image photo response functions.
