The connections within these networks may be strong or weak, and the information that a cell sends out may increase the activity of some of its neighbors and inhibit the activity of others. Each time a connection is used, it gets stronger. Densely connected neighborhoods of brain cells carry out computations that are integrated with information coming from other neighborhoods, often involving feedback loops.
Many computations are carried out simultaneously the brain is a massively parallel information processor. Computer-based methods for enabling such intense language practice under the supervision of a speech-language pathologist are becoming available. This question is hard to answer, because brain activity is like the activity of a huge city. A city is organized so that people who live in it can get what they need to live on, but you can't say that a complex activity, like manufacturing a product, is 'in' one place. Raw materials have to arrive at the right times, subcontractors are needed, the product must be shipped out in various directions.
It's the same with our brains. We can't say that language is 'in' a particular part of the brain. It's not even true that a particular word is 'in' one place in a person's brain; the information that comes together when we understand or say a word arrives from many places, depending on what the word means. So listening, understanding, talking, and reading involve activities in many parts of the brain. However, some parts of the brain are more involved in language than other parts.
Most of the parts of your brain that are crucial for both spoken and written language are in the left side of the cortex of your brain the left hemisphere , regardless of what language you read and how it is written. We know this because aphasia is almost always caused by left hemisphere injury, not by right hemisphere injury, no matter what language you speak or read, or whether you can read at all. Areas in the right side are essential for communicating effectively and for understanding the point of what people are saying. Our brains are somewhat plastic — that is, their organization depends on our experiences as well as on our genetic endowment.
Bilingual speakers develop special skills in controlling which language to use and whether it is appropriate for them to mix their languages, depending on whom they are speaking to. These skills may be useful for other tasks as well. What is aphasia like?
Is losing language after brain damage the reverse of learning it? People who have difficulties speaking or understanding language because of brain damage are not like children.
For Fodor, mental states are token neural states which are syntactically characterized. Synapses training Phase 1: Training of inter-area synapses within the feature network In a first phase, the network is trained to recognize objects without the presence of words. Brain potential and functional MRI evidence for how to handle two languages with one brain. Although it is difficult to find a specific cortical location for this area, the existence of cortical regions especially devoted to lexical aspects of language has been hypothesized in cognitive neuroscience for decades Ward The last analyses we performed were aimed at comparing L1 and L2 within and between each group. That is, they are both conjunctions, they have the same components, they only differ in the arrangement of the components within the structure, and the content of each is determined by their structure, their parts, and the arrangement of the parts within the structure. Tye argues that on a proper understanding of the thesis that mental images have spatial properties, it does not straightforwardly undermine the claim that mental representation has a linguistic structure.
Using language involves many kinds of knowledge and skill. People with aphasia have different combinations of things that they can still do in an adult-like way and things that they now do clumsily or not at all. In fact, we can see different patterns of profiles of spared and impaired linguistic abilities across different people with aphasia.
Therapy can help aphasic people to improve on or regain lost skills and make the best use of remaining abilities. Adults who have had brain damage and become aphasic recover more slowly than children who have had the same kind of damage, but they continue to improve slowly over decades if they have good language stimulation and do not have additional strokes or other brain injuries. What about dyslexia, and children who have trouble learning to talk even though they can hear normally?
Why do people have reading difficulties? Research suggests that dyslexics have trouble processing the sounds of language and have difficulty relating the printed word to sounds. There is solid evidence that appropriate language-based therapy is effective for children with developmental disorders of reading and language, including stuttering.
This new information has become available because of major improvements in our ability to see what is happening in the brain when people speak or listen, and from the accumulation and analysis of many years of detailed aphasia test data. For over a hundred years, research in neurolinguistics was almost completely dependent on the study of language comprehension and production by people with aphasia.
These studies of their language ability were augmented by relatively crude information about where the injury was located in the brain. Neurologists had to deduce that information, such as it was, by considering what other abilities were lost, and by autopsy information, which was not often available. J oan M aling Ch.

Language and the Brain: Representation and Processing (Foundations of Neuropsychology) [Yosef Grodzinsky, Lewis P. Shapiro, David Swinney] on. A syntactic representation is simply the wrong vehicle for belief obsession. Chapter 2 - Remarks on the Architecture of Language Processing Systems.
In lieu of an abstract, here is a brief excerpt of the content: Reviewed by:. Language and the brain: Representation and processing ed. Language and the brain: Representation and processing. These results demonstrate that a number of regions in the human brain are truly domain-general and plausibly support flexible human behavior. How do circuits of neurons in our brains construct and hold the meaning of a sentence?
To start to address this question, we measured neural activity from the surface of the human brain in patients being mapped out before neurosurgery, as they read or listened to sentences.
In many electrodes, neural activity increased steadily over the course of the sentence, but the same was not found when participants processed lists of words or pronounceable nonwords, or grammatical nonword strings "Jabberwocky". This build-up of neural activity appears to reflect neither word meaning nor syntax alone, but the representation of complex meanings. Skip to main content.
Our Research Program Language is one of the few uniquely human cognitive abilities and a foundation of human culture and civilization. Our research centers around three key questions : What is the internal architecture of the language network? How does the language network interact with other large-scale networks in the human brain e. What is the nature of inter-individual differences in the neural instantiation of language processing, and how do these differences relate to differences in behavior and genetic make-up?
Key Discoveries 1. High-level language-processing brain regions are functionally specialized for language Language has been argued to share cognitive and neural machinery with a number of cognitive processes, including arithmetic processing, general working memory, cognitive control, and musical processing.
