Neurolinguistics
central questions of neurolinguistics
Aphasia is an acquired language disorder, often defined as a focal lesion (i.e., a lesion of one or more specific areas).
Acquired disorders are also caused by progressive neurological diseases, such as dementias
disorders that are found in children who have not experienced any specific lesion event, are of interest to neurolinguistics
Neurolinguists also study the language development of children with nonspecific developmental disorders affecting language.
For a neurolinguist, an essential source of knowledge is the possibility of measuring brain activity during language tasks in normal and damaged brains
The measurement of dynamic activity in the brain during language tasks by methods such as EEG (electroencephalography), PET (positron emission tomography), fMRI (functional magnetic resonance imaging), and MEG (magnetic encephalography) is an important tool for research.
views on the relation between brain and language
Localism tries to find locations or centers in the brain for different language functions
Associationism situates language functions in the connections between different areas of the brain,
Dynamic localization of function assumes that functional systems of localized subfunctions perform language functions.
Holistic theories consider many language functions to be handled by widespread areas of the brain working together.
Evolution-based theories stress the relationship between how the brain and language evolved over time
interdisciplinary character of the field
The many disciplines dealing with neurolinguistics provide inspiration and energy, to the field. They introduce many different kinds of data, theories, and models for research.
The editors of Studies in Neurolinguistics in the 1970s described the series as “heterogeneous both in theoretical perspective and in topical coverage”
interdisciplinary focus includes the fields of linguistics, neuroanatomy, neurology, neurophysiology, philosophy, psychology, psychiatry, speech pathology, and computer science
These disciplines may be the ones most involved
in neurolinguistics, but several other disciplines are also highly relevant, having contributed to theories, methods, and findings in neurolinguistics
Include neurobiology, anthropology, chemistry, cognitive science, and artificial intelligence.
Neurolinguistics studies the relation of language and communication to different aspects of brain function
it tries to explore how the brain understands and produces language and communication
Apart from neurology and linguistics, psychology is another central source discipline for neurolinguistics.
became the established term for the field in the 1960s, under the influence of the Chomsky an boost to linguistics and the development of psycholinguistics as a defined field.
even though the field of neurolinguistics is frankly interdisciplinary, there is a common theme of the relationships between language and the brain
