Hemisphere refers to the two different sides of the brain. It states that the two sides of the brain control different parts of the body. There are two sides the left and the right side. The left side of the brain controls the right side of the body and it processes all analytical thinking. The right side of the brain controls the left side of the body and also controls peoples feelings. The corpus collasum is the the layer of neutrons that connect the two sides of the brain and allow them to interact with eachother. Paul Broca's research concerned the comparative study of the skulls of the races of humankind, work that aided the development of modern physical anthropology. He originated methods to study the brain's form, structure, and surface features and sections of prehistoric skulls. His discovery of the brain's speech centre was the first anatomical proof of localization of brain function. In the early 1950s Roger Sperry set out to find how a creature would behave if all such commissures were severed resulting in a ‘split brain’. To his surprise he found that monkeys and cats with split brains act much the same as normal animals. However, where learning was involved the creatures behaved as if they had two independent brains. Thus if a monkey was trained to discriminate between a square and a circle with one eye, the other being covered with a patch, then, if the situation was reversed the animal would have to relearn how to make the discrimination. Where as when he studied a 49-year-old man whose brain had been split to prevent the spread of severe epeliptic convulsions from one side to the other. He found that, though normal in other ways, the patient showed the effect of cerebral disconnection in any situation that required judgment or interpretation based on language. Sperry's work immediately posed the problem of whether there is any comparable specialization inherent in the human right-hand brain. Wernicke's area is named after Carl Wernicke, a German neurologist and psychiatrist who, in 1874, hypothesized a link between the left posterior section of the superior temporal gyrus and the reflexive mimicking of words and their syllables that associated the sensory and motor images of spoken words. This proved a theory that brain injuries caused aphasia and would effect peoples speech.
The Lobe most responsible for vision is Occpital lobe.The lobe most responsible for math calculations is the left side of your brain.
The lobe most responsible for judgment, reasoning and impulse control is the right side of your brain.
