Chapter 1 Flashcards
Plasticity
The concept that in the immature brain some functional areas are not established and that unestablished areas may assume any one of a variety of functions.
Travis:
First identified stuttering to be the result of brain dysfunction, specifically the imbalance between the two hemispheres.
Pinker:
Synthezised the linguistic and nerologic bases of language
computed tomography (CT)
X-ray imaging technique in which the brain is viewed at different depths; the various views are correlated by computer to show structural lesions in the brain.
aphasia
Acquired disorder of language caused by brain damage; may affect comprehension or expression of language and any modality (Spoken, written, or gestural language)
Carl Wernicke:
Identified an auditory center for speech associate with comprehension of speech, opposing Broca, who identified the expressive center.
Chomsky:
Language is innate and implies a biologic, neurologic, and genetic basis for language.
Goodglass and Kaplan:
Neuropsychologists and students of Geshwind
Liepmann:
First to identify the apraxias of motor execution
asymmetry
Disproportion or inequality between two corresponding parts around the center of an axis.
Lenneberg:
Wrote “The Biological Foundations of Langage in January 15, 1967
behavioral neurology
A specialty in neurology emphasizing clinical and research skills in neurodegenerative diseases and neuralbehavioral syndromes.
association fiber tracts
The fiber bundles that form connections between and within the association areas of the brain.
2004
New ASHA clinical and academic standards
dorsal
Pertaining to the back; posterior.
cephalic
of or relating to the head; directed towards or situated on, in, or near the head.
rostral
Toward the nasal or an oral regions; superior in relation to the spinal cord and anterior in relation to the brain.
Ogle:
Identified a writing center in the brain independent of Broca’s area.
The first textbook of language disorders in the field of speech pathology:
Wepman’s “Recovery from Aphasia”
Penfield:
First to use cortical mapping for identifying areas of language and speech functions in the brain
localization of function
A particular structure in the nervous system assigned to a specific function (E.G., Broca’s area is the localized area for language expression).
ventral
Toward the belly or abdomen opposite of dorsal.
Geschwind influenced these 3 fields:
Linguistics
Psychology
Philosophy
Frontal Lobe
Language and speech expression
