1

What are the two parts of the Auditory forebrain?

Medial geniculate body
Auditory cortex

2

What does the medial geniculate body do?

Processes and relays auditory info to the auditory cortex

3

The auditory cortex is made up of:

A1 and A2

4

Afferent:

MGB --> A1 and A2

5

Sensory association area is:

Temporal and parietal lobes

6

MGB --> A1 and A2 :

Afferent

7

The speech area of the brain is:

Wernicke's and Broca's areas

8

Wernicke's area sends projections to Broca's area via:

Arcuate fasciculus

9

Wernicke's and Broca's areas are the:

Speech area of the brain

10

The temporal and parietal lobes are apart of the:

Speech association area

11

Tonotopic organization also exists in the auditory cortex. A1 =
A2 =

A1 = sharp tuning
A2 = broad tuning

12

What is characteristic delay?

Interaural time difference

13

What is characteristic intensity difference?

Interaural intensity difference

14

What are the 4 complex features the auditory forebrain can detect?

Frequency modulation
Temoral modulation
Spectral modulation
Auditory attention neurons

15

What do auditory attention neurons respond to?

Novel sounds

16

What are the cortexes with speech and hearing?

Primary auditory cortex
Secondary auditory cortex: Wernicke's area
Broca's area: Motor speech center

17

What does the primary auditory cortex do?

Processes complex acoustic stimuli

18

What does the secondary auditory cortex (Wernicke's area) do?

Understands written and spoken language

19

Broca's area is considered the:

Motor speech center

20

Damage to Wernicke's area/A2 results in:

Receptive aphasia
Unable to understand speech and language

21

Damage to Broca's area/motor speech center:

Expressive aphasia
Unable to produce speech and language

22

Damage to arcuate fasciculus:

Conduction aphasia
Unable to repeat what was just said
