How our brain Works

1. What does the word "hemisphere" refer to when talking about the brain?
Is one of the two regions of the eutherian brain that are delineated by the median plane. The brain can thus be described as being divided into left and right cerebral hemispheres. Each of these hemispheres has an outer layer of grey matter called the cerebral cortex that is supported by an inner layer of white matter.
2. What are the major differences between the left and right sides of the brain?
The left side of the brain is the seat of language and processes in a logical and sequential order. The right side is more visual and processes intuitively, holistically, and randomly
3. What is the corpus collasum?
Also known as the colossal commissure, is a wide, flat bundle of neural fibers beneath the cortex in the eutherian brain at the longitudinal fissure. It connects the left and right cerebral hemispheres and facilitates interhemispheric communication
4. Explain the study performed by Paul Broca in which he discovered "Broca's Area."
The process of identifying the parts of the brain that are involved in language began in 1861, when Paul Broca, a French neurosurgeon, examined the brain of a recently deceased patient who had had an unusual disorder. Though he had been able to understand spoken language and did not have any motor impairments of the mouth or tongue that might have affected his ability to speak, he could neither speak a complete sentence nor express his thoughts in writing. The only articulate sound he could make was the syllable “tan”, which had come to be used as his name.
5. Explain the study conducted by Roger Sperry in regard to "split brain."
Roger Wolcott Sperry was a neuropsychologist, neurobiologist and Nobel laureate who, together with David Hunter Hubel and Torsten Nils Wiesel, won the 1981 Nobel Prize in Medicine for his work with split-brain research..Split-brain is a lay term to describe the result when the corpus callosum connecting the two hemispheres of the brain is severed to some degree. The surgical operation to produce this condition is called corpus callosotomy and is usually used as a last resort to treat intractable epilepsy.
6. Explain the study conducted by Karl Wernicke which led to the discovery of Wernicke's Area."
Wernicke's area is the region of the brain where spoken language is understood. Neurologist Carl Wernicke is credited with discovering the function of this brain region.
