The neurolinguistic is the discipline that studies the human brain mechanisms making possible the understanding, production and knowledge of the language, also well spoken than written.
The neurolinguistic has an interdisciplinary nature, with contributions of Linguistics, Neurobiology and computational linguistics. The concept of Neurolinguistics is commonly associated with the study of aphasia, i.e. the linguistic deficiency caused by specific forms of brain injury.
For this reason, it says that the aphasiologie is the historical basis of the neurolinguistic. However, over the years, this discipline has experienced an important development by introducing new technologies, thus extending its field of action.
For example, the modern brain imaging techniques have provided new knowledge concerning the anatomical organization of the functions of the language. With these images, it is possible to analyze the use of energy in the brain during language processing tasks.
Electrophysiological techniques EEG (electroencephalography) and EMG (electromyography), on the other hand, offer a resolution at the level of the milliseconds, even if the nature of the brain mechanism that produces electrical signals in the scalp (scalp) is not known, making its interpretation difficult. EEG and EMG are used to demonstrate cognitive computational theories of the architecture of the language, without taking into account the neurobiological implementation.
The neurolinguistic also appealed to the calculation model to demonstrate the inconsistency of the specific assumptions on the neural organization of language.
Finally, we will retain the neurolinguistic has a strong link with Psycholinguistics, who studies the cognitive mechanisms of language through the traditional techniques of experimental psychology.
