the pupil and the iris respond to light which lets us see from the optic nerve
The cerebrum is responsible for higher brain functions such as thinking, decision-making, and voluntary movements. It also plays a role in processing sensory information and emotions.
I'm not sure but I think what happens is: In humans, both eyes look forward from the front of the head and so when you look at an object, each eye sees a slightly different image. The brain interprets the impulses coming from your two eyes as one image as result, you can see in the dimensions, which means you can tell how near or far away and image is. (the bold italic words are my best answer.) Again, I'm not totally sure that's the correct answer but I'm guessing so.
The two halves of the cerebrum are the left and right hemispheres.

The cerebrum is divided into two hemispheres, each of which is further divided into four lobes: frontal, parietal, temporal, and occipital. So, in total, the cerebrum is divided into eight lobes.

The groove that divides the cerebrum in two hemispheres is called the longitudinal fissure. It separates the left and right hemispheres of the brain and is where the corpus callosum connects the two hemispheres.
Two, right and left.
The thalamus and hypothalamus.

The two hemispheres of the cerebrum are separated by a structure called the corpus callosum. This is a thick band of nerve fibers that allows communication and coordination between the two hemispheres of the brain.
