The cells in the cerebral cortex are neurons and unmylinated axons, hence the term grey matter.
Feature detectors are specialized nerve cells in the visual cortex that respond to visual stimuli.
cerebral cortex
feature detection
Specialized cells, called retinal ganglions, together with bipolar cells, amacrine cells, and horizontal cells, carry the visual information to the optic nerve (cranial nerve 2). This nerve then carries the information from the retina at the back of the eye to the visual cortex in the occipital lobe (back of the head).

Motor neurons are nerve cells that are located in the motor region of the cerebral cortex or brain stem.

Binocular
In the primary visual cortex. Information passes from the retina to the bipolar cells, these impulses travel through the optic nerve, which is made up of the axons of ganglion cells, and extend to several regions of the brain including the thalamus. The impulses are then sent further along neurones, to the primary visual cortex, where further processing of the information occurs.
The rod cells in the back of your eye become active in the dark; the cone cells are active in the light. All the nerve impulses from the eyes go back to the visual cortex in the back of the brain where they are decoded, or interpreted, as visual experience.

the occipital lobe is the primary vision center - visual information is received through the retinal cells, then passed on to the lateral geniculate bodies of the thalamus, which then project to the occipital lobe or "visual cortex".
