Broca's Case Study

Superior Essays
One states that a fact is a reasoned idea, which contains multiple evidence for its existence. A theory is a dynamic, and official statement of guidelines upon a subject, and based off of ideas which explain the premise. The argument of “ facts are need to establish theories but theories are needed to make sense of facts” can be supported by the areas of knowledge in Social Sciences, Psychology, as well as in Natural Science, Biology. Both of these areas correlate in studying humans to the extend of behaviour, and biological structures and their functions upon the behaviour.

In Psychology, in the department of biological level of analysis, scientists research on how biology may affect human behaviour, it focuses on brain, hormones, and genetics.

Broca investigated multiple patients who suffered from strokes. In 1861 Broca discovers that the damage in the left frontal lobe of the brain was the cause why patients were unable to understand, speak complex sentences and problems with speech. His famous patient was called Tan, because that was the only word he could say, but also due to anonymity. After Tan’s death, his autopsy revealed that the disability was the result of a specific brain damage in the left frontal lobe, called The Broca's area. Now these conditions of trauma are called Broca’s aphasia. The brian injury in the left, frontal lobe, affected the patient in their speech since that area is the control system of speech, problem solving, and movement, if it’s damaged then it affects these criterias, which is proven in Broca’s Case Study of Tan. This investigation was one of the ones which helped initiate the theory of Localization of Function, since the theory was finally established in 1860s. It demonstrates how facts were used to commence a theory, in sense of the data collected. Broca was provided with the qualitative data, such as behavioural patterns, and the physical state of the brain, which allowed Broca to utilize reasoning in order to expand the theory of …show more content…
It consists of three main principles: (1) All living organisms are composed of cells. They may be unicellular or multicellular. (2) The cell is the basic unit of life. (3) Cells form from preexisting cells. (They are not derived from spontaneous generation.) These principles can be proven by multiple existing organisms in our world, such as Paramecium, a unicellular organism which still completes all the function of a living organism. It nutrition is based on smaller organisms and taking them in through endocytosis, a process in which a cell allows molecules/organism inside of it’s outer shell. Its metabolism is initiated in cytoplasm where it catalyzes metabolic reactions, and diffuse CO2, as excretion material, out of its membrane. Paramecium’s specific structure of cilia ( small hairs outside of the membrane) allow the organism to respond and move due to detected stimuli from its cilia. In order to reproduce it follows through both sexual, and asexual reproduction, mitosis and meiosis. This organism is a fact which was first encountered, and compared to numerous other organisms, such as humans, who also reproduce, process metabolism, etc. Grouping similar organism together allows scientist to utilize their data collection in order to reason their theory. However, in order to establish a theory and

    Membrane Self-Assembly Processes: Steps Toward the First Cellular Life by Pierre-Alain Monnard & David W. Deamer Summary: To summarize, early cells must have had a membrane to encapsulate its components and keep them within the cell. This membrane was made up of amphiphiles. This membrane was very permeable and as a result, passive diffusion occurred. Later on this membrane evolved to be a little impermeable as to keep the metabolic reactions and catalysts that drive these reactions within the cell. The membranes were also heterozygous in that it was made of more than one amphiphile.…

    The nitrogen containing BP, Zoledronic acid, is one of the most commonly implicated drugs in BRONJ cases due to its higher potency and multimodal effect on bone remodeling and oral mucosa. 20-22 ZA induced BRONJ models are known to show classical BRONJ lesions with macroscopic features of bone necrosis, soft tissue inflammation and sequestration in various animal models, ranging from rats to large animal models like sheep. 16,17,23 However, the exposure of bone to the oral environment, either through a tooth extraction, artificially induced periodontitis, or repeated trauma is a pre-requisite for the initiation of BRONJ lesion in animal models. 24-27…

    There are two ways an animal can reproduce: first is by laying eggs and giving birth to living organisms. The first way is usually done by bird’s amphibians like frogs, nearly all species of fish, reptiles and a number of mammals. The second way is done by mostly all mammals, some reptiles, frogs and few aquatic creatures like sharks. The ingredients need for animal reproduction is two cells called sperm which is produced by male and egg cells produced by female. The cells get combined called…

    Broca’s aphasia was first described by Paul Broca who was a well-known physician in the 19th century. Broca had a patient who, prior to his death, could only say the word “tan.” Broca claimed that the patient had “a brain lesion in the posterior portion of the left inferior frontal gyrus” (Cognitive Neuroscience: The biology of the mind, pg. 472). This lesion is what caused the patient to have such severe language issues.…

    Psychology is the scientific study of the human mind and its functions. Wilhelm Wundt first began research for psychology psychologists have developed from around the world to bring us five main perspectives of psychology, known as, the five schools of thought. The five schools of thought help people to understand why people do certain motions, how people interact with each other, where we develop our mannerisms, and to have a deeper understanding of the human mind, through: biological, psychodynamic, behavioral, cognitive and humanistic perspectives. Biological psychology is the study of the physiological bases of behavior, which follows “the relationship between psychological processes and the underlying psychological events” (Britannica,…

    Biological Psychology is one such perspective. It assists nurses in understanding patients' behavior using the physiological changes in their bodies. As a point of view, biological psychology believes that biological function and structure determines the behavior of a person (Baker, 2007). An example is a case where the patient is an elderly woman who is always in pain, appears agitated, lacks concentration and whose memory is deteriorating. A nurse can apply biological psychology to assist the patient in diagnosing the patient.…
