Q

where is the primary auditory cortex located

A

superior temporal lobe

18
Q

provide the significance for Heschl’s gyrus

A

it is theorized to be a location where pitch is represented

19
Q

what does amusia mean

A

tone deaf

20
Q

true or false - the primary auditory cortex demonstrates tonotopic organization

A

true

21
Q

describe the importance for the secondary audio cortex and the association cortex

A

understanding cognitive representation of the environment, processing melody and spatial grouping

22
Q

what happens when pitches are different

A

there are two separate stream of notes that are perceived

23
Q

explain the galloping effect

A

when the notes are very similar, the two streams can get crossed over

24
Q

true or false - the superior temporal lobe is involved in melody processing

A

false - it is the superior temporal gyrus

25
Q

what are melodic contours

A

progression of notes, sequence of melody

26
Q

list the 3 functions of the superior temporal lobe

A
  1. categorical perception of major and minor chords
  2. processing melodic intervals
  3. processing melodic contours
27
Q

what are the two structures involved in multi-sensory/multimodal integration

A

parietal cortex and superior temporal sulcus

28
Q

what is an example of multimodal integration

A

copying a series of notes on the piano + seeing how the person’s fingers move on the piano -> combining auditory and visual input

29

A

multi sensory integration

30

temporal

31
Q

A

spectral resolution

32
Q

what does the dual pathway model of auditory processing hypothesize

A

two pathways which originate from the primary auditory cortex contribute to processing higher order properties

33

where

35
