In the human brain, what is the area that is involved in language processing, speech production and comprehension?
"spatial processing. In general, neuroimaging studies have found that reading involves three overlapping neural systems: networks active in visual, orthography-phonology (Angular gyrus), and semantic functions (Anterior temporal lobe with Broca's and Wernicke's area). However, these neural networks are not discrete, meaning these areas have several other functions as well. The Broca's area involved in executive functions helps the a reader to vary depth of reading comprehension and textual engagement in accordance with reading goals. Reading comprehension and vocabulary are inextricably linked together. The ability to decode or identify and pronounce words is self-evidently important, but knowing what the words mean"
"a whole series of relatively large areas of the brain have been found to be involved in speech processing. In more recent research, subcortical regions (those lying below the cerebral cortex such as the putamen and the caudate nucleus) as well as the pre-motor areas (BA 6) have received increased attention. It is now generally assumed that the following structures of the cerebral cortex near the primary and secondary auditory cortices play a fundamental role in speech processing: The left hemisphere is usually dominant in right-handed people, although bilateral activations are not uncommon in the area of syntactic processing. It"
"formation of explicit long-term memory modulated by the amygdala. The temporal lobe holds the primary auditory cortex, which is important for the processing of semantics in both speech and vision in humans. Wernicke's area, which spans the region between temporal and parietal lobes, plays a key role (in tandem with Broca's area in the frontal lobe) in speech comprehension. The functions of the left temporal lobe are not limited to low-level perception but extend to comprehension, naming, and verbal memory. The medial temporal lobes (near the sagittal plane) are thought to be involved in encoding declarative long term memory. The"
"both Wernicke's area and the angular gyrus, both prominent anatomical structures of the brain that are involved in language cognition, processing, and comprehension of both written and spoken language. This is the region of the brain wherein “Mentalese”, a term coined by Steven Pinker to explain the brain’s language that translates itself into written and spoken language, is processed. According to Pinker, “knowing a language is knowing how to translate Mentalese into a string of words and vice versa.” The lTPJ succeeds in this matter by taking in observations from external environments, such as conversations, making connections in the brain"
"to language comprehension. Generally, the neural structures that support language production are predominantly in the left hemisphere for most individuals creating an hemispheric asymmetry, which results in differential language processing abilities of the two hemispheres. Because of its spatially close ties and intergation with language production, left hemisphere language comprehension seems to be driven by expectancy and context in a top-down manner, whereas the right hemisphere seems to integrate information in a bottom-up manner. The PARLO framework suggests that both prediction and integration occur during language processing but rely on the distinct contributions of the two hemispheres of the brain."
"in the inferior frontal cortex, close to Broca's area, one of the hypothesized language regions of the brain. This has led to suggestions that human language evolved from a gesture performance/understanding system implemented in mirror neurons. Mirror neurons have been said to have the potential to provide a mechanism for action-understanding, imitation-learning, and the simulation of other people's behaviour. This hypothesis is supported by some cytoarchitectonic homologies between monkey premotor area F5 and human Broca's area. Rates of vocabulary expansion link to the ability of children to vocally mirror non-words and so to acquire the new word pronunciations. Such speech"
"into an understandable form. This occurs primarily in the inferior frontal cortex, specifically in an area known as Broca's area. Next, the brain must plan how to physically create the sounds necessary for speech by linking the planned speech with known sounds, or phonemes. While the location of these associations is not known, it is known that the supplementary motor area plays a key role in this step. Finally, the brain must signal for the words to actually be spoken. This is carried out by the premotor cortex and the motor cortex. In most cases, speech production is controlled by"
"systems are activated through similar neuronal processes but independently placed along the network. The left inferior frontal gyrus is also extremely important for language comprehension and production due to the fact that most language processing takes place in the left hemisphere. Commonly known as ""Broca's area"", people with damage in this region often have a type of non-fluent aphasia known as Broca's aphasia. Broca's area is located on the left hemisphere of the brain and encompasses Brodmann's area 44 and 45. Both overall have contributions to verbal fluency, but each has its own specific contribution. Area 44 is involved in"
"speech production is articulation, which is the execution of the articulatory score by the lungs, glottis, larynx, tongue, lips, jaw and other parts of the vocal apparatus resulting in speech. The motor control for speech production in right handed people depends mostly upon areas in the left cerebral hemisphere. These areas include the bilateral supplementary motor area, the left posterior inferior frontal gyrus, the left insula, the left primary motor cortex and temporal cortex. There are also subcortical areas involved such as the basal ganglia and cerebellum. The cerebellum aids the sequencing of speech syllables into fast, smooth and rhythmically"
"the area of his brain that was important for speech production. The area of the brain that Broca identified is now known as Broca's area; damage to this section of the brain can lead to Expressive aphasia. Karl Wernicke also used postmortem studies to link specific areas of the brain with speech production. However his research focused more on patients who could speak, however their speech made little sense and/or had trouble understanding spoken words or sentences. His research in language comprehension and the brain also found it to be localized in the left hemisphere, but in a different section."
"modern imaging techniques. The discipline of linguistics dedicated to studying the neurological aspects of language is called neurolinguistics. Early work in neurolinguistics involved the study of language in people with brain lesions, to see how lesions in specific areas affect language and speech. In this way, neuroscientists in the 19th century discovered that two areas in the brain are crucially implicated in language processing. The first area is Wernicke's area, which is in the posterior section of the superior temporal gyrus in the dominant cerebral hemisphere. People with a lesion in this area of the brain develop receptive aphasia, a"
"Auditory cortex The auditory cortex is the part of the temporal lobe that processes auditory information in humans and other vertebrates. It is a part of the auditory system, performing basic and higher functions in hearing, such as possible relations to language switching. It is located bilaterally, roughly at the upper sides of the temporal lobes – in humans on the superior temporal plane, within the lateral fissure and comprising parts of Heschl's gyrus and the superior temporal gyrus, including planum polare and planum temporale (roughly Brodmann areas 41, 42, and partially 22). Unilateral destruction, in a region of the"
"Language processing in the brain Language processing refers to the way humans use words to communicate ideas and feelings, and how such communications are processed and understood. Language processing is considered to be a uniquely human ability that is not produced with the same grammatical understanding or systematicity in even human's closest primate relatives. Throughout the 20th century the dominant model for language processing in the brain was the Geschwind-Lichteim-Wernicke model, which is based primarily on the analysis of brain damaged patients. However, due to improvements in intra-cortical electrophysiological recordings of monkey and human brains, as well non-invasive techniques such"
"cortex), and in the insula. There also appears to be activation in the right hemisphere during most language tasks. Language-related areas are dedicated to certain components of language processing (e.g. lexical semantics). These areas are functionally characterized by linguistically pertinent systems, such as phonology, syntax, and lexical semantics—and not in speaking, reading, and listening. In the normal human brain, areas associated with linguistic processing are less rigid than previously thought. For example, increased familiarity with a language has been found to lead to decreases in brain activation in left dorsolateral frontal cortex (Brodmann areas, 9, 10, 46). Bilingualism involves the"
"to the parts of the cerebral cortex. Motor portions of language are attributed to Broca's area within the frontal lobe. Speech comprehension is attributed to Wernicke's area, at the temporal-parietal lobe junction. These two regions are interconnected by a large white matter tract, the arcuate fasciculus. Damage to the Broca's area results in expressive aphasia (non-fluent aphasia) while damage to Wernicke's area results in receptive aphasia (also called fluent aphasia). Explicit or declarative (factual) memory formation is attributed to the hippocampus and associated regions of the medial temporal lobe. This association was originally described after a patient known as HM"
"is concentrating their attention on retrieving the memory. The student is exhibiting cognitive control over their memory. This type of processing is directed, in part, by the ventrolateral prefrontal cortex (VLPFC). Pars triangularis is found in this region. When reading aloud, people must decode written language to decipher its pronunciation. This processing takes place in Broca's area. The reader might use previous knowledge of a word in order to correctly vocalize it, or the reader might use knowledge of systematic letter combinations, which represent corresponding phonemes. Scientists can learn about what the brain is doing while people process language by"
"speech, and that speech processing seems to occur within Wernicke's area. Hearing plays an important part in both speech generation and comprehension. When speaking, the person can hear their speech, and the brain uses what it hears as a feedback mechanism to fix speech errors. If a single feedback correction occurs multiple times, the brain will begin to incorporate the correction to all future speech, making it a feed forward mechanism. This is apparent in some deaf people. Deafness, as well as other, smaller deficiencies in hearing, can greatly affect one's ability to comprehend spoken language, as well as to"
"grammar, slow speech production and poor sentence comprehension. The inferior frontal gyrus, is a gyrus of the frontal lobe that is involved in timing events and reading comprehension, particularly for the comprehension of verbs. The Wernickes area is located on the posterior section of the superior temporal gyrus and is important for understanding vocabulary and written language. The primary auditory cortex is located on the temporal lobe of the cerebral cortex. This region is important in music processing and plays an important role in determining the pitch and volume of a sound. Brain damage to this region often results in"
"directed at either the anterior or the posterior part of Broca's area. The results from this experiment conclusively distinguished anatomical specialisation within Broca's area for different components of language comprehension. Here the results showed that under rTMS stimulation: To summarise, the work above shows anatomical specialisation in Broca's area for language comprehension, with the anterior part of Broca's area responsible for understanding the meaning of words (semantics) and the posterior part of Broca's area responsible for understanding how words sound (phonology). Recent experiments have indicated that Broca's area is involved in various cognitive and perceptual tasks. One important contribution of"

Supramarginal gyrus The supramarginal gyrus is a portion of the parietal lobe. This area of the brain is also known as Brodmann area 40 based on the universally used brain map created by Korbinian Brodmann to define the structures in the cerebral cortex. It is probably involved with language perception and processing, and lesions in it may cause receptive aphasia. The supramarginal gyrus is part of the somatosensory association cortex, which interprets tactile sensory data"
"Lingual gyrus The lingual gyrus, also known as the ""medial occipitotemporal gyrus"", is a brain structure that is linked to processing vision, especially related to letters. It is thought to also play a role in analysis of logical conditions (i.e. logical order of events) and encoding visual memories. The lingual gyrus is named after its shape which is somewhat similar to a tongue. It is believed that a hypermetabolism of the lingual gyrus is associated with visual snow. Contrary to the name, the region has little to do with speech. The lingual gyrus of the occipital lobe lies between the"
"influenced by the kidneys – when blood pressure falls, the renin released by the kidneys stimulates a need to drink. The hypothalamus also regulates food intake through autonomic signals, and hormone release by the digestive system. While language functions were traditionally thought to be localized to Wernicke's area and Broca's area, it is now mostly accepted that a wider network of cortical regions contributes to language functions. The study on how language is represented, processed, and acquired by the brain is called neurolinguistics, which is a large multidisciplinary field drawing from cognitive neuroscience, cognitive linguistics, and psycholinguistics. The cerebrum has"
"mind tasks in children. In addition to these hypotheses, there is also evidence that the neural networks between the areas of the brain responsible for language and theory of mind are closely connected. The temporoparietal junction has been shown to be involved in the ability to acquire new vocabulary, as well as perceive and reproduce words. The temporoparietal junction also contains areas that specialize in recognizing faces, voices, and biological motion, in addition to theory of mind. Since all of these areas are located so closely together, it is reasonable to conclude that they work together. Moreover, studies have reported"
"Brodmann area 22 Brodmann area 22 is one of Brodmann's area's – cytoarchitecturally defined regions of the brain. It is part of the superior temporal gyrus included in the language processing region known as Wernicke's area. Brodmann area 22 is the cytoarchitecturally defined posterior superior temporal gyrus on the left side of the brain. In the left hemisphere this area helps with generation and understanding of individual words. On the right side of the brain it helps to discriminate pitch and sound intensity, both of which are necessary to perceive melody and prosody. This part of the brain is active"
"lobe, which in turn connects with inferior frontal gyrus. In both humans and non-human primates, the auditory dorsal stream is responsible for sound localization, and is accordingly known as the auditory 'where' pathway. In humans, this pathway (especially in the left hemisphere) is also responsible for speech production, speech repetition, lip-reading, and phonological working memory and long-term memory. Studies of present-day humans have demonstrated a role for the ADS in speech production, particularly in the vocal expression of the names of objects. For instance, in a series of studies in which sub-cortical fibers were directly stimulated interference in the left"
"the left hemisphere. In a series of studies, Wilder Penfield, among others, probed the brains of both right-handed (generally left-hemisphere dominant) and left-handed (generally right-hemisphere dominant) patients. They discovered that, regardless of handedness, the left hemisphere was almost always the speech controlling side. However, it has been discovered that in cases of neural stress (hemorrhage, stroke, etc.) the right hemisphere has the ability to take control of speech functions. Verbal Comprehension is a fairly complex process, and it is not fully understood. From various studies and experiments, it has been found that the superior temporal sulcus activates when hearing human"
"Brodmann area 21 Brodmann area 21, or BA21, is part of the temporal cortex in the human brain. The region encompasses most of the lateral temporal cortex, a region believed to play a part in auditory processing and language. Language function is left lateralized in most individuals. BA21 is superior to BA20 and inferior to BA40 and BA41. This area is also known as middle temporal area 21. It is a subdivision of the cytoarchitecturally defined temporal region of cerebral cortex. In the human it corresponds approximately to the middle temporal gyrus. It is bounded rostrally by the temporopolar area"

Area 45 is a part of the anterior inferior frontal gyrus and is involved in semantic processing. Characteristics of Broca's aphasia include agrammatic speech, relatively good language comprehension, poor repetition, and difficulty speaking. People with Broca's aphasia do not have deficits in language comprehension; however, they speak mostly in short utterances of a few words at a time, mostly nouns. Their speech is limited to short sentences, and producing sound is a very difficult task for those affected. The left IFG has"

Damage to the left lateral sulcus has been connected with difficulty in processing and producing morphology and syntax, while lexical access and comprehension of irregular forms (e.g. eat-ate) remain unaffected. Moreover, the circuits involved in human speech comprehension dynamically adapt with learning, for example, by becoming more efficient in terms of processing time when listening to familiar messages such as learned verses.

"speech sounds, and the neurological apparatus required for acquiring and producing language. The study of the genetic bases for human language is at an early stage: the only gene that has definitely been implicated in language production is FOXP2, which may cause a kind of congenital language disorder if affected by mutations. The brain is the coordinating center of all linguistic activity; it controls both the production of linguistic cognition and of meaning and the mechanics of speech production. Nonetheless, our knowledge of the neurological bases for language is quite limited, though it has advanced considerably with the use of"

In 2006, Brown, Martinez and Parsons found that listening to a melody or a sentence resulted in activation of many of the same areas including the primary motor cortex, the supplementary motor area, the Brocas area, anterior insula, the primary audio cortex, the thalamus, the basal ganglia and the cerebellum. A 2008 study by Koelsch, Sallat and Friederici found that language impairment may also affect the ability to process music. Children with specific language impairments, or SLIs were not as proficient at matching tones to one another or at keeping tempo with a simple metronome as children with"
