Visual stimuli that are perceived by our eyes arrive in the thalamus, which processes the information and sends it to our cerebral cortex, or more specifically the visual cortex in our occipital lobe.
Both thalamus and cerebral cortex are part of the brain, though their function vastly differs. Thalamus relays sensory information to the cerebral cortex and regulates sleep, alertness, and consciousness, while cerebral cortex manages a vast array of functions, from controlling our movements to becoming the network central to the other parts of the brain – including helping us speak, write, and listen. Cerebral cortex also include other lobes beside the occipital, which are frontal lobe, temporal lobe, and parietal lobe, which handles many primary functions in our brain.
