The Wernicke-Geschwind Model is broken down into 3 forms of pathways:
*hint: A.C.V.R.
pathways associated with auditory comprehension, pathways associated with visual comprehension, and pathways for reading
Heard words are processed along the ________ pathways to the ________ (Heschl’s Gyrus) where cortical processing of auditory input is processed.
auditor pathways; primary auditory cortex
After the auditory input has passed through the auditory pathways and through Heschl’s Gyrus, information is then sent to ________ where words are recognized and connection to their meaning begins.
Wernicke’s Area
*auditory information is first processed in cortex in Heschl’s Gyrus in the superior temporal gyrus (sound discrimination occurs).
Word meanings are sent from ______ via the ______ to _______.
*starts at area where word meaning is associated, then travels through a pathway that leads to the front of the brain*
Wernicke’s Area; Arcuate Fasciculus; Broca’s Area
It is here where words are converted to a code for muscular movements of speech.
Broca’s Area
Output from Broca’s Area is then sent to the _______ regions in which controls the movement of muscles involved in the production of speech.
Primary Motor Cortex
The visual information taken from written words is sent from visual areas in the ______ to the _______
*hint: where in the cortex is it dedicated to visual sensory input*
occipital lobe; Angular Gyrus
Motor representations for phonemes are stored in regions associated with _______.
motor output (Broca’s Area)
*supported by links to the inferior premotor and motor cortex from Broca’s Area*
Auditory representations of a phoneme are likely to be found in ______.
auditory association cortex (near Heschl’s Gyrus)
Visual representations are supported by links to _________.
(inferior) visual association areas
*make up part of the ventral “what” stream of visual processing*
This area is in charge of sequencing motor patterns for the production of phonemes and their combinations.
Broca’s Area
The anterior (pars triangularis) and ventral (pars orbitalis) portions of Broca’s Area are involved in _______
Semantic Processing
The _____ (pars opercularis) portion of Broca’s Area appears to be engaged in both ______ and ______ processing
posterior; syntactic; phonological
This area is in charge of oral language comprehension and formulation of linguistic concepts:
A.) Broca’s Area
B.) Heschl’s Gyrus
C.) Wernicke’s Area
D.) Angular Gyrus
E.) None of the above
C - Wernicke’s Area
