At a first glance, hemispheres look like mirror images (identical). However, science has been proving since 1968 effectively through examinations of positron emission tomography (PET), functional magnetic resonance imaging (fMRI), electroencephalography (EEG) and regional cerebral blood flow (rCBF), the existence of anatomical asymmetries, neurochemical and functional, thereby designating the hemispheric specializations.
Paul Broca (1860), through work and biopsies found that the language processing was given in the left hemisphere. Broca also addressed the relationship between the use of the hand and speech, and attributed the innate superiority of the left hemisphere in right-handed. Created then, the "Broca’s Act", that the speech controller hemisphere is opposite to the dominant hand. …show more content…
While maintaining the ability of fluent speech (even if meaningless) state similar to the hemiplegic patient with the pusher syndrome. Sperry (1966) observed in a group of patients undergoing corpus callosum sectioning surgery, when an object was presented in the right visual field he answered (named) what he was seeing, but the same object was presented in the left visual field, the patient refused to be seeing anything but identified him if I could touch it with your right hand, where he concluded that the patient could not name the visual stimulus that was limited to the right hemisphere, as this is the left hemisphere of the speech

    Broca's Aphasia Chapter Summary

    2. Chapter 5 of the Ogden text describes the cases of Luke and Beth, two individuals who both were diagnosed with aphasia, whose cases and lives are extremely different. After introducing the reader to Luke and Beth, Ogden briefly describes aphasia and the most common types. She mentions the popular trend to not classify aphasia, but rather to describe the symptoms being exhibited. Broca’s aphasia is then described; this is most frequently associated with expressive aphasia and is characterized by the nonfluency of speech, language impairment, a patient’s right arm or hand going numb, and occasionally oral apraxia.…

    Paul Broca's Analysis

    A woman’s brain on average weighed 181 grams less than a man’s brain according to scientist Paul Broca’s data. Broca and his team were trying to scientifically prove that woman were inferior to men. With a women’s brain weighing less than a man’s, Broca believed this finding meant that women were less intelligent than men. Broca’s experiment was flawed, he lacked constant variable which separates the good experiments from the bad. Broca’s experiment was conducted in 1872, which was a time when women were supposed to be the care takers of the household and rarely had prestigious jobs or an education like men did.…

    Healing Pig Demonstration Essay

    The squealing pig demonstration of Galen is one of the most famous single physiological demonstrations of all time that even Leonardo da Vinci was inspired to produce a beautiful drawing of the recurrent laryngeal nerves (Gross, 1997). According to Gross (1998), it was Galen’s squealing pig demonstration that brought the first experimental and publicly repeatable evidence that the brain controls behavior. In his time, Galen even made lengthy arguments against Stoic philosophers, implying in Galenic writings that brain is the organ of thought. Before this famous demonstration of his, the brain was only recognized with little importance since it is based only from indirect references from anatomy. This only presents us with how Galen deals with…

    Why Is Fibrodysplasia Important?

    The patient may speak in short or incomplete sentences, speak in sentences that seem to make no sense, and substitute one word or sound for another. The patient may also say words that are unrecognizable, not be able to comprehend a conversation being held, and write sentences that do not make sense. The degree of damage of the brain results to the severity of the signs and symptoms that the victims possess. There are at least three types of different aphasia cases in which the victims possess varied characteristics. In nonfluent aphasia, the people struggle to get words out, creating short sentences that leave words out.…

    If we consider the words “KEY . RING” and tell the patient to look at the dot separating them, the patient will be able to say “RING”, but the patient would be able to draw a “KEY”. This shows how language is lateralized to the left hemisphere as the word “RING” is perceived by the right visual field being connected to the left hemisphere; Furthermore, that the right hemisphere does not contain this function because the patient was unable to say “KEY”. 2 c. Performing test like these allow us to understand lateralization in the general population because in an intact brain, we cannot reliably test lateralization since we cannot isolate functions to a specific hemisphere.…

    Broca Research Paper

    A simple evening eating pizza, socializing and playing cards might seem like a simple event, but in reality to complete such tasks, the brain is continuously adapting to the environment. The Broca area is involved in speech production which means that it generates every word that you will be pronouncing during your visit at your friends. The Broca also is involved in language processing which helps one speak clearly. During the evening out, the Broca will be producing the words and phrases needed to socialize with your friends. During the card game, you need to speak to get your value across to the other players, so your Broca will need say words such as "check" and "fold" if the friendly game indeed is poker.…

So what happens when there is disconnect between our brains and our ability to communicate? Neurologists have termed the word aphasia which refers to “the collective deficits in language comprehension and production that accompany neurological damage” (Cognitive Neuroscience: The biology of the mind, pg. 472).…

    The Split Brain Theory

    “Never one person or groups of people exclusively used more of their left side of the brain or more of the right side” was concluded by Dr. Gayatri Devi, the professor of neurology at New York (“Left brain right brain theory”). This is a reference to the myth that people think they are more dominant on their left side of their brain and vice versa. The split-brain theory, better known as the left-brain, right-brain theory, is a theory that distinguishes people as “left brained” or “right brained”, which had originated when neurological patients’ left side and right side of their brain was surgically disconnected. This became more significant in the 1960’s and 1970’s when neuropsychologist Roger W. Sperry conducted 16 split-brain operations…

The growth of the brain extend the cognitive skills and motor skills (Pg 215). In the brain, there are two hemispheres; left and right. The right hemisphere controls the creative side while the left brain controls logical tasks. Surprisingly, there is a difference in lateralization for boys and girls. "…
