What is the motor speech area in the left frontal lobe called?
The production of speech is very complex and involves many parts of the brain, but the Broca's area of the left frontal lobe of the cerebrum is responsible for its final production. Why is it on the left and not the right? There may be no other answer as to why.
Damage to Broca's area and Wernicke's area of the brain can cause?
Damage to Broca's area can cause expressive aphasia, resulting in difficulties with speech production. Damage to Wernicke's area can cause receptive aphasia, resulting in difficulties with understanding language and forming coherent sentences. Both areas are important for language processing and communication.
What is a specialized motor speech area located at the base of the of the precentral gyrus called?
The specialized motor speech area located at the base of the precentral gyrus is called Broca's area. It is responsible for language production and coordinating the movements necessary for speech. Damage to this area can result in expressive language deficits known as Broca's aphasia.
What is the area that controls the comprehension of language in the brain?
The area that controls the comprehension of language in the brain is called Wernicke's area, located in the left hemisphere of the brain in most individuals. Damage to this area can result in receptive aphasia, where language comprehension is impaired.
What are the kinds of aphasia?
Aphasia is an impairment in the comprehension and/or production of language. The two main headings are fluent and non-fluent aphasia.WERNICKE'S APHASIAANOMIC APHASIACONDUCTION APHASIAUNUSUAL APHASIA SYNDROMESMIXED AND GLOBAL APHASIAThis is an addition to the above-mentioned answer.motor aphasia = caused by any damages to Broca's areasensory aphasia:auditory aphasia = caused by any damages to Wernicke's areavisual aphasia = caused by any damages to angular gyrusGlobla aphasia = caused by any damages or obstruction to "middle cerebral artery" which supplies the Broca's area, Wernicke's area and angular gyrus.
What does damage to the Wernickes area do?
Damage to the Wernicke's area in the brain can result in receptive aphasia, also known as Wernicke's aphasia. This condition affects the ability to understand language, resulting in difficulty with comprehension and producing meaningful speech. People with damage to this area may speak in ways that are fluent but nonsensical.
Difficulty in forming words would indicate an injury to what part of the brain?
Difficulty in forming words is often associated with an injury to the left hemisphere of the brain, particularly in areas such as Broca's area or the motor cortex. These areas are responsible for language production and speech articulation. Injuries to these regions can result in conditions like aphasia or apraxia, leading to difficulties in forming words.
What function affects Broca's area?
Broca's area is the area of the brain responsible for speech production, language processing, and language comprehension, as well as controlling facial neurons. First discovered in 1861, Broca's area was named after Pierre Paul Broca. Broca discovered the area after studying the brain of a patient with a speech impairment after his death. Broca's area is connected to the Wernick's area of the brain by the arcuate fasciculus, which is a pathway made of neurons. It is found in the frontal lobe of the cortex, within the inferior frontal gyrus. It is comprised of two primary parts: the Pars triangularis and the Pars opercularis. The Pars triangularis is located in the anterior portion of Broca's area. Researchers believe that this area of the brain is responsible for helping the human brain interpret different stimulus modes. It is also where verbal conducts are programmed in the brain. The Pars opercularis is located in the posterior region of Broca's area. It is believed that this area supports only one stimulus mode, rather than multiple modes like the Pars triangularis. This portion of Broca's area is also thought to coordinate the organs used for speech in order to produce language. This conclusion has been drawn because the Pars opercularis of Broca's area is located near areas that are related to motor skills. If the Broca's area is damaged, the person is said to suffer from Broca's area aphasia. This condition is also called expressive aphasia, nonfluent aphasia, or motor aphasia. A person suffering from this condition is unable to put together sentences that are grammatically complex. In addition, the sentences typically contain very few words related to content. Despite the person's difficulty in putting together sentences, a person with a damaged Broca's area is generally capable of comprehending language without a problem. In some cases, however, the person may have difficulty with understanding a few words used in a sentence with complex syntax. These individuals typically have damage only in the posterior portion of Broca's area, a condition referred to as Wernicke's aphasia. Those suffering from Wernicke's aphasia may have somewhat normal speech, though it tends to be vague or even meaningless. Individuals who stutter have also been found to have a smaller Pars triangularis and a decreased overall amount of activity in the Broca's area. On the other hand, these individuals tend to have more activity in the right hemisphere of the Broca's area. It is believed that this increased activity is to compensate for the overall decrease.
Which cerebral lobe contains Bronca's area?
Broca's area is located in the frontal lobe of the brain, usually in the left hemisphere. It plays a crucial role in speech production and language processing. Damage to this area can result in expressive language difficulties known as Broca's aphasia.
What is the Difference between dysarthria and expressive aphasia?
Both dysarthria and aphasia are abnormalities of speech. The chain of speech and abnormalities are as follow:i. Hearingii. Understanding -- Aphasiaiii. Thought & word finding -- Aphasiaiv. Voice productionv. Articulation -- DysarthriaAphasia refers to the abnormalities in understanding, thought and word finding.Dysarthria refers to the difficulties in speech at any level such as breathing, vocal cord, larynx, palate, tongue and lips.The common types of aphasia are Wernicke's aphasia and Broca's aphasia.Wernicke's area (Broadmann's area 22) in cerebral cortex receives visual input from occipital lobe and auditory input from temporal lobe, it permits the understanding of spoken and written language and enable a person to interprete it. Destruction of Wernicke's area in dominant hemisphere cause receptive aphasia. The patient is unaware of the speech by others and also himself. So, he speaks long and meaningless speech. Since the Broca's area is intact, he can produce smooth speech.Broca's area (Broadmann area 44, 45) in cerebral cortex is motor speech area. It is connected to the Wernicke's area by arcuate fasciculus. It receives impuls from Wernicke's area and converted it into the motor command and sends to cerebral cortex to be converted into action of muscles involved in speech.If destructed, the patient retains the ability to think. The patient speaks short but meaningful speech with great effort. The sentence is not complete. This is expressive aphasia.For dysarthria, lesions of upper motor neuron, lower motor neuron, basal ganglia, cerebellum or extrapyramidal system leads to disturbance of the intergration of speech production and the speech rhythm. The speech of the patient is not clear but very complete and meaningful. Patient can interprete other's speech and respond to it correctly.
Damage to this cortical area will cause difficulty in understanding speech?
Damage to the Wernicke's area, located in the left temporal lobe, can result in receptive aphasia where individuals have difficulty understanding speech and language, often leading to fluent but nonsensical speech. This area plays a crucial role in language comprehension rather than production.
What part of the brain is damaged if you can hear but not understand?
If a person is hearing words and are not understanding their meaning it does not mean they have lobe damage. They would have lobe damage if they were not able to hear the words at all. This means that they just do not understand the meaning of the specific words or they do not understand what a person meant by what they said.
