Flashcards in 13 Deck (22):
What are the two parts of the Auditory forebrain?
Medial geniculate body
What does the medial geniculate body do?
Processes and relays auditory info to the auditory cortex
The auditory cortex is made up of:
A1 and A2
MGB --> A1 and A2
Sensory association area is:
Temporal and parietal lobes
MGB --> A1 and A2 :
The speech area of the brain is:
Wernicke's and Broca's areas
Wernicke's area sends projections to Broca's area via:
Wernicke's and Broca's areas are the:
Speech area of the brain
The temporal and parietal lobes are apart of the:
Speech association area
Tonotopic organization also exists in the auditory cortex. A1 =
A1 = sharp tuning
A2 = broad tuning
What is characteristic delay?
Interaural time difference
What is characteristic intensity difference?
Interaural intensity difference
What are the 4 complex features the auditory forebrain can detect?
Auditory attention neurons
What do auditory attention neurons respond to?
What are the cortexes with speech and hearing?
Primary auditory cortex
Secondary auditory cortex: Wernicke's area
Broca's area: Motor speech center
What does the primary auditory cortex do?
Processes complex acoustic stimuli
What does the secondary auditory cortex (Wernicke's area) do?
Understands written and spoken language
Broca's area is considered the:
Motor speech center
Damage to Wernicke's area/A2 results in:
Unable to understand speech and language
Damage to Broca's area/motor speech center:
Unable to produce speech and language
