The hypothalamus sets up an opponent process so that certain incoming visual information "blocks" other incoming visual information.

Question: Why are you limited to how much visual information you are able to process at any one given moment?

The thalamus, which directs information to the brain, can only filter so much information at any one moment in time.

The occipital lobe is smaller than the other cerebral lobes, so it can't process as much information.

The neurons in your visual cortex are wired in an inhibitory way.

Answer:

"The neurons in your visual cortex are wired in an inhibitory way. "

Explanation:

The visual cortex is the main cortical region of the brain that obtains, assimilates, and procedures visual evidence communicated from the retinas. It is in the occipital lobe of the main cerebral cortex, which is in the furthermost posterior region of the brain. Also recognized as the striate cortex, or simply V1, the main visual cortex is situated in the most posterior share of the brain's occipital lobe. In fact, a great portion of the main visual cortex cannot be understood from the exterior of the brain, since this cortex lies on either adjacent of the calcarine fissure.
