Paul Broca was a French physician, anthropologist and anatomist. He specialized in the study of the word. His most important discovery was the “Broca Zone”. Broca's area is also called Broca's convolution. It is the left hemisphere of the brain that contains neurons and these neurons are involved in vocal function. Broca's area is located in the third frontal convolution, just anterior to the facial area. This area is connected to other regions of the brain. This area involves understanding language associated with hand movements. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"? Get an original essay History tells us that the real motivation behind this research was a person named Louis Victor Leborgne who lost the ability to speak when he was 30 years old. He could only utter one single-syllable word: Tan. After the accident, when he arrived at the hospital, he had a speech impediment. He couldn't speak properly for two or three months. Apart from the inability to speak, no other serious trauma was observed. After 10 years of the accident, Tan was hospitalized again because many other health problems had started. There he met the French doctor “Pierre Paul Broca” for the first time. Broca's main area of ​​interest was the word. This case of Tan intrigued him. Broca decided to check the patient's other faculties. It was a complicated matter since Tan was right-handed, not only could he not speak but he couldn't even write. Communication proved complex. However, he could make gestures with his left hand that sometimes became incomprehensible. Surprisingly, he was good with numbers. He knew exactly how long he had been in the hospital. His other faculties had degraded but, in a way, he remained as sharp as ever. When it comes to the “Broca zone”, it remains hopeless. Broca called it “deficit aphemia, or aphasia, the loss of articulate speech.” Subsequent results include a biopsy of his brain after his death. It revealed a great lesson in the frontal area. After a few months, Broca met another patient Lazare Lelong. Unlike Tan, he could say five to six words such as "yes, no, three, always and Lelo (his attempt to pronounce his name)". After his death, his brain was also autopsied. Here Boca discovered that there is a specific area in the brain, if it is affected, a person is unable to produce meaningful sounds and eventually loses the ability to communicate. Other researchers and neurologists have also worked in this area. The German doctor and medical writer Johann Gesner published a treatise on the topic “Language Amnesia.” Another neurologist, Carl Wernicke, also worked on fluent aphasia. In 1824, the French physician Jean-Baptise Bouillard took Gesner's idea forward and proposed the remarkable idea that the brain could be localized. The research method adopted by Paul Broca was the Case Study. He studied almost 25 patients with almost the same problem. He observed them and also interviewed them. The best case study was that of Leborgne's brain which offered the opportunity to test and refine the theories of Bouillard and Auburtin. Finally, in 1865, a full four years after Tan's famous brain autopsy, Broca was finally ready to claim that speech production was localized to a specific part of the left frontal lobe, the region that now bears his name. By then, he had described the brains of 25 other patients who had suffered from aphemia and had come to conclude that the articulation of speech was indeed controlled by the left frontal lobe, just as Bouillard and Auburtin had suspected. Brain function was not del.
