Visual stimuli that arrive in the thalamus are relayed to the

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.

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
