Lecture 1. The Concept of Auditory Processing Flashcards
(34 cards)
Parts of the left hesmisphere is known to be impliacted in what?
parts of the left hemisphere known to be implicated in language function/dysfunction
Name The Auditory Cortex and Association Areas
Primary auditory area
- Heschel’s gyrus located in the sylvian fissure and posterior 1/3 of the superior temporal gyrus
Secondary auditory area
- Posterior superior temporal lobe
Tertiary auditory area
- Posterior-inferior part of the temporal lobe
Auditory association area
- Includes Wernicke’s area - superior temporal gyrus
Where is the lateral fissure?
The lateral fissure runs horisontally on both hemispheres but more on left hemisphere
Runs between Broca’s area and Wernikes area
the sylvian fissure is a maker for____
the sylvian fissure is a marker for linguistic capacity
Perisylvian refers to
Perisylvian refers to the area around the sylvian fissure
the angular gyrus is involved in
the angular gyrus is involved in the processing of auditory and visual input and language comprehsnion
What is the angular gyrus essential role
Essential role in the integration, processing and connection of these different functional areas
________is connected to both broca’s and werkicke’s area which in turn are connected to each other by _________
Angular gyrus connected to both Broca’s area and Wernicke’s areas, which in turn are connected to each other by a large bundle of nerve fibers, the arcuate fasciculus
Auditory signals are processed by _____
Auditory signals are processed by Heschl’s gyrus
Phonemic analysis probably takes place in ________
the adjacent auditory association cortex (Wernicke’s area)
Speech is encoded by
more anterior regions, among them Broca’s area, that directs the adjacent motor cortex to produce appropriate movements for speech production
Damage to any of these regions near the ________ impairs language repetition, and is the hallmark of perisylvian aphasias
Sylvian fissure
Damage to any of these regions near the sylvian fissure impairs language repetition, and is the hallmark of ________
perisylvian aphasias
What is perisylvian aphasia
- Broca’s aphasia = expressive
- Wernicke’s aphasia = receptive
- Global Aphasia is also a PA
________ is an impairment of language, affecting the production or comprehension of speech and the ability to read or write
Aphasia
Define aphasia
Aphasia is an impairment of language, affecting the production or comprehension of speech and the ability to read or write.
* where expressice and receptive language abilities
Aphasia is always due______
Brain injury
Aphasia is most commonly following what?
Aphasia is most commonly following a stroke.
Aphasia’s may also occur by what?
Aphasia also may occur with other cerebral disorders
* brain tumors
* head trauma
* dementia
* Multiple Sclerosis MS
* Infection
Where is Wernicke’s area?
Wernicke’s area lies in the left temporal lobe, adjacent to the primary auditory area
Wernicke’s area helps us ____
Wernicke’s area helps us to understand language
Language development/usage can be seriously impaired by damage to where?
Wernicke’s area = sesnory/receptive apahsia
Patients are unaware of their aphasia
Wernicke’s Aphasia
trouble reading and writing, trouble understanding speech of others
Wernicke’s Aphasia
