What part of the eye send message to the brain?

Answer 1

The eye connects with with the brain via the optic nerve. Inevitably, it is slightly more complicated than that. The retina of the eye does considerable processing of visual information and the eye/visual context can be considered a single system. Interestingly, by accidents of evolution, the retina is "inside out" - the nerves are on the wrong side and the visual cortex is at the back of the brain making the optic nerve much longer than it needs to be.

Answer 2

The image on the retina is converted into nerve impulses by the cones and rods, then this impulse is sent to the brain by the optic nerves (Cranial Nerve II) which travels to the brain, and finally to the occipital lobes where it is interpreted as an image.

Yay this works perfectly!! THANK YOU

Answer 3

The retina (the blind spot of the eye) is the place in the eye which is most affected when there's light around. Too much light can blind you. Furthermore, the retina sends information by light (which is telling the brain that there is either too little or too much light).

Answer 4

Messages from the eyes to the brain do not travel via the spinal column; they go straight from the retinal cells through the optic nerve to the visual cortex of the brain.

Answer 5

After the refracted light from the lens hits the retina, it is passed through the optic nerve to the cerebrum in the brain.

Answer 6

The optic nerve, acting on stimuli from the retina.
