What Side Of The Brain Controls Speech

Why Creationists Deny Scientific Evidence

The left side of the brain controls speech. As well as the Brocos area, another area that controls speech is called the Wernickes area. It deals with understanding speechand language. That is how we can understand others and react with proper emotion. It is also connected to the sensory cortex.

People who have damaged this speech center are not able to understand what they hear. However, they do not have problems with word formation. This condition is called Wernickes aphasia.

People with damage to both areas have a condition called global aphasia.

D Localization Of Integration: Ifg Or Stg

Psycholinguistic models on sentences comprehension assume a processing phase during which syntactic and semantic information interact with each other and are integrated to achieve interpretation. Some models hold that the different information types interact at any time during comprehension or after an initial syntactic structure building phase . Neuroimaging approaches have discussed two different regions as possible sites where integration takes place. Some researchers assume that the final integration of syntactic and semantic information takes place in the left posterior STG, whereas others assume that unification of different language-relevant information types is located in the left IFG. Interestingly, the crucial neuroimaging studies these proposals are based on all show activation in both the IFG and the STG .

It is clear, however, that the posterior temporal cortex is crucial in binding the verb and its arguments and more generally for integration across domains and that the inferior frontal gyrus support different language aspects within its subregions . Interactions between semantic aspects and syntax, as seen in studies manipulating semantics by lexical-semantic ambiguity , semantic relatedness , or semantic constraint due to animacy , are located in the more anterior portions of the IFG , but not in BA 44 . From this, we may conclude that the IFG’s role as a region of combining semantic and syntactic information may be restricted to its more anterior parts.

Pars Orbitalis Of The Inferior Frontal Gyrus

Structural connectivity

TheBA47 ROI was consistently found to be associated with the inferior occipito-frontal fasciculus . In all subjects, streamlines consistent with the IOFF passed through both the BA47 and MTG ROIs.

Figure 8. Pathways associated with the BA47 ROI . Streamline tractography results from two subjects are presented as exemplars. The inferior occipito-frontal fasciculus as well as a group of IOFF fibers associated with the posterior MTG ROI were identified.

Resting-state functional connectivity

The functional connectivity map for BA47 consisted of six clusters . The largest cluster was centered in the IFG, extending to pars opercularis , inferior precentral gyrus , and the temporal pole . Other clusters were in the MTG bilaterally, the right IFG, a left posterior region which included parts of the left angular gyrus and the superior temporal gyrus , and the left medial frontal cortex .

Where Is The Speech Center Of The Brain

The entire cerebral cortex contains two hemispheres. They are, for the most part, symmetrical in function. The cerebellum also contains two hemispheres and is located at the back of the brain, the part of the brain responsible for our sense of balance.

For a majority of the population, the speech center of the brain is located in the left hemisphere .

But its important to remember that all functionality of the brain is a mutual effort of all four lobes of the brain. Without the proper functioning of all four lobes, we would have difficulty with basic motor function, sight, speech, and higher thinking processes handled by the frontal lobe.

Major Structures And Functions Of The Brain


Outside the specialized world of neuroanatomy and for most of the uses of daily life, the brain is more or less an abstract entity. We do not experience our brain as an assembly of physical structures if we envision it at all, we are likely to see it as a large, rounded walnut, grayish in color.

This schematic image refers mainly to the cerebral cortex, the outermost layer that overlies most of the other brain structures like a fantastically wrinkled tissue wrapped around an orange. The preponderance of the cerebral cortex is actually a recent development in the course of evolution. The cortex contains the physical structures responsible for most of what we call ”brainwork”: cognition, mental imagery, the highly sophisticated processing of visual information, and the ability to produce and understand language. But underneath this layer reside many other specialized structures that are essential for movement, consciousness, sexuality, the action of our five senses, and moreall equally valuable to human existence. Indeed, in strictly biological terms, these structures can claim priority over the cerebral cortex. In the growth of the individual embryo, as well as in evolutionary history, the brain develops roughly from the base of the skull up and outward. The human brain actually has its beginnings, in the four-week-old embryo, as a simple series of bulges at one end of the neural tube.

Exercises And Critical Thinking

  • Do you think that animals experience emotion? What aspects of brain structure might lead you to believe that they do or do not?
  • Consider your own experiences and speculate on which parts of your brain might be particularly well developed as a result of these experiences.
  • Which brain hemisphere are you likely to be using when you search for a fork in the silverware drawer? Which brain hemisphere are you most likely to be using when you struggle to remember the name of an old friend?
  • Do you think that encouraging left-handed children to use their right hands is a good idea? Why or why not?
  • Role Of The Temporal Lobe

    Many of the neuroimaging studies on language comprehension report activation in the anterior and posterior temporal lobe. While some studies concluded that the anterior and posterior temporal regions react specifically to semantic or syntactic aspects, others challenged this view by arguing either that the anterior temporal lobe or the posterior temporal lobe is not domain specific .


    A number of fMRI studies reporting activation in the temporal lobe investigated semantic and syntactic processes by systematically varying the presence/absence of semantic and syntactic information in a within-subject design. Those studies that compared sentences to word lists found the lateral anterior temporal lobe to activate more strongly for sentences than for word lists . As this increase of activation in the anterior STG/STS is present even when comparing meaningless pseudoword sentences with meaningless pseudoword lists, this region has been interpreted to support the construction of phrase structure in particular . One study investigating the processing of sentences containing syntactic and semantic violations found that, compared with baseline, syntactic violations led to an increased activation in the anterior STG, whereas semantic violations did not . Moreover, studies testing semantics by comparing real-word stimuli with pseudo-word stimuli reported no main effect of semantics in anterior STG/STS .

    The function of a part of the human brain known as Wernicke’s area is to enable us to comprehend written and spoken language. It is located posterior to the primary auditory complex in the left temporal lobe of the cerebral cortex, the part of the brain where information processing of all kinds takes place.

    Wernicke’s area is connected to another brain region involved in language processing known as Broca’s area. Located in the lower portion of the left frontal lobe, Broca’s area controls motor functions involved with speech production. Together, these two brain areas help us to speak as well as to interpret, process, and understand spoken and written language.

    The Brain Is Flexible: Neuroplasticity

    The control of some specific bodily functions, such as movement, vision, and hearing, is performed in specified areas of the cortex, and if these areas are damaged, the individual will likely lose the ability to perform the corresponding function. For instance, if an infant suffers damage to facial recognition areas in the temporal lobe, it is likely that he or she will never be able to recognize faces . On the other hand, the brain is not divided up in an entirely rigid way. The brains neurons have a remarkable capacity to reorganize and extend themselves to carry out particular functions in response to the needs of the organism and to repair damage. As a result, the brain constantly creates new neural communication routes and rewires existing ones. Neuroplasticity refers to the brains ability to change its structure and function in response to experience or damage. Neuroplasticity enables us to learn and remember new things and adjust to new experiences.

    Although neurons cannot repair or regenerate themselves as skin or blood vessels can, new evidence suggests that the brain can engage in neurogenesis, the forming of new neurons . These new neurons originate deep in the brain and may then migrate to other brain areas, where they form new connections with other neurons . This leaves open the possibility that someday scientists might be able to rebuild damaged brains by creating drugs that help grow neurons.

    The Brain Behind Language Learning

    There are so many different factors to take into consideration when it comes to identifying why a student is having trouble understanding language and learning to read. A physical or innate problem, such as the way the brain works, is often a factor that is overlooked and may be hard to pinpoint.

    Several areas of the brain must function together in order for a person to develop, utilize and understand language. Lets take a look.

    • Brocas area: Located in the frontal lobe of the brain, is linked to speech production, and recent studies have shown it to also play a significant role in language comprehension. Brocas area works in conjunction with working memory to allow a person to use verbal expression and spoken words.
    • Wernickes area: Located in the cerebral cortex, this is the part of the brain involved in understanding written and spoken language. Damage to this area results in speech that is unable to be understood by others.
    • Primary auditory cortex: Located in the temporal lobe and connected to the auditory system, this area is organized so that it responds to neighboring frequencies in the other cells of the cortex. It is responsible for identifying pitch and loudness of sounds.
    • Angular gyrus: Located in the parietal lobe of the brain, this area is responsible for several language processes, including number processing, spatial recognition and attention.

    In Conclusion: Brain Anatomy

    The human brain is an incredibly complex, hardworking organ. As one-half of the human nervous system, the brain structure oversees nearly all of the body’s operations, including how we move, think, feel and understand ourselves and the world around us. And knowing all this brain anatomy is important. From the cerebrum, cerebellum and the brain stem, to all the parts in between: this three-pound organ is what makes us humans, well, human.

    In recent decades, there has been an explosion of research into language processing in the brain. Its now generally accepted that the control of speech is part of a complex network in the brain.

    The formation of speech requires many different processes, from putting thoughts into words, forming a comprehensible sentence, and then actually making the mouth move to make the correct sounds.

    There are several areas of the brain known to play a role in speech:

    In 2013, a group of researchers from the University of Edinburgh published the largest study to date about the correlation between bilingualism and progression of dementia and other cognitive diseases like Alzheimers. The subjects were 648 patients from Hyderabad, the capital city of the state of Telangana, in India. Telugu and Urdu are the predominant languages in that region, where English is also commonly used. Most of the residents of Hyderabad are bilingual, 391 of whom were part of the study. The conclusion was that the bilingual patients had developed dementia, on average, four and a half years later than the monolingual ones, strongly suggesting that bilingualism has a deep impact on neurological structures and processes.

    The process of acquiring a second language might be one we dedicate a lot of time and effort to, at school for example, but in some cases it happens naturally . So how can it be that this process, regardless of how it takes place, has such a big impact on the brain?

    Thought As A Human Ability

    Before proceeding further, remember that thought is all that activity of the human mind that is obtained thanks to the intellect. That is, it is the product of the process of thinking, or the process of the mind itself. Through thought, we obtain abstractions, reflections

    Cognitive theory, typical of psychology, allows dividing the different types of thinking into: critical, deductive, inductive, creative or lateral, intuitive thinking, etc. One of these types of thinking is the one that concerns us: analytical thinking.

    The cerebrum is the largest part of the brain. Located in the front and middle part of the brain, it accounts for 85% of the brain’s weight. Of the three main parts of the brain, the cerebrum is considered the most recent to develop in human evolution. The cerebrum is responsible for all voluntary actions , communication, emotions, creativity, intelligence and personality.

    The Old Brain: Wired For Survival

    The brain stem is the oldest and innermost region of the brain. Its designed to control the most basic functions of life, including breathing, attention, and motor responses . The brain stem begins where the spinal cord enters the skull and forms the medulla, the area of the brain stem that controls heart rate and breathing. In many cases the medulla alone is sufficient to maintain life animals that have the remainder of their brains above the medulla severed are still able to eat, breathe, and even move. The spherical shape above the medulla is the pons, a structure in the brain stem that helps control the movements of the body, playing a particularly important role in balance and walking.

    Running through the medulla and the pons is a long, narrow network of neurons known as the reticular formation. The job of the reticular formation is to filter out some of the stimuli that are coming into the brain from the spinal cord and to relay the remainder of the signals to other areas of the brain. The reticular formation also plays important roles in walking, eating, sexual activity, and sleeping. When electrical stimulation is applied to the reticular formation of an animal, it immediately becomes fully awake, and when the reticular formation is severed from the higher brain regions, the animal falls into a deep coma.

    For more than a century, it’s been established that our capacity to use language is usually located in the left hemisphere of the brain, specifically in two areas: Broca’s area and Wernicke’s area .

    Likewise, what controls language in the brain? The cerebellum is located at the back of your brain. The cerebellum is involved in coordinating voluntary muscle movements like opening and closing your mouth, moving your arms and legs, standing upright, and maintaining balance. It also controls language processing.

    In this way, what part of the brain controls language comprehension?

    Wernicke’s area is a critical language area in the posterior superior temporal lobe connects to Broca’s area via a neural pathway. Wernicke’s area is primarily involved in the comprehension. Historically, this area has been associated with language processing, whether it is written or spoken.

    What brain areas are involved in language processing?

    We now know that numerous regions in every major lobe are involved in our ability to produce and comprehend language.
