Temporal lobe and Occipital lobe

Question 1

Primary auditory cortex
- location
- function

Answer 1

• BA 41 and BA 42
• responsible for the basic auditory functions

Question 2

Secondary auditory cortex
- location
- function

Answer 2

• BA 22
• higher auditory processing, eg music

Question 3

Wernicke’s area
- location
- function

Answer 3

• posterior to BA 22
• understanding speech (making sense of the words)

Question 4

Inferior temporal gyrus
- location
- function

Answer 4

• under the collateral sulcus
• visual recognition (the apple story of senses)

Question 5

Medial temporal lobe

Answer 5

related to the hippocampus (learning and memory)

Question 6

Significance of planum temporale
- how did we know the size??

Answer 6

• the reason why humans can have complicated speech
• this region refers to the Superior Temporal Gyrus, BA 22 and Wernicke’s area
• it is up to 10x bigger in the left hemisp than the right

=> measurements include surface area, cytoarchitectonic studies, asymmetry in white matter volume and myelination

Question 7

Primary visual cortex
- location
- function

Answer 7

• BA 17, along the CALCARINE FISSURE
• processing orientation, spatial frequency, color of objects

Question 8

Visual association cortex (secondary areas)

Answer 8

• higher order of processing visual info, motion, shape

Question 9

Importance of the calcarine fissure

Answer 9

In our visual field, information from the bottom will be presented above the calcarine fissure and vice versa
