parietal lobe

Question 1

define sensory homunculus

Answer 1

a map along the cerebral cortex of where each part of the body is processed

Question 2

what does sensory homunculus do
A) processes visual info
B) recognise nature of stimuli
C) decides appropriate response
D) recognise where the sensory information comes from

Answer 2

D) recognise where the sensory information comes from

Question 3

how is the anterior part of the parietal cortex called:

A) Postcentral gyrus
B) Somatosensory cortex
C) Superior parietal lobule
D) Inferior parietal lobule

Answer 3

B) Somatosensory cortex

Question 4

all the cortical powers dedicated to processing sensory information are the same: true or false

Answer 4

false. there are different processing powers and sensitivity will depend on how much processing power is dedicated to that structure

Question 5

which Brodmann area is related to posterior parietal cortex:

A) 22
B) 37
C) 44, 45
D) 1,2,3
E) 37
F) 5, 7, 39, 40
G) 17
H) 41, 42

Answer 5

F) 5, 7, 39, 40

Question 6

what does posterior parietal cortex allow us to do
A) processes visual info
B) recognise nature of stimuli
C) decides appropriate response
D) recognise where the sensory information comes from

Answer 6

D) recognise where the sensory information (stimuli) comes from

Question 7

posterior parietal cortex is important for… (2)

A) problem-solving
B) planning
C) language comprehension
D) attention
E) movement
F) integrating visual, auditory and somatosensory information
G) memory formation

Answer 7

D) attention
F) integrating visual, auditory and somatosensory information

Question 8

damage to the posterior parietal cortex results in…

A) alcoholism
B) prosopagnosia
C) neglect
D) pareidolia

Answer 8

C) neglect

Question 9

match the different types of neglect with its correct definition:

A) Sensoryneglect
B) Conceptual neglect
C) Hemiasomatognosia
E) Hemineglect
D) Motorneglect

a) fewer movements in the contralateral space
b) incoming sensory information from the contralateral hemispace is ignored
c) patient can’t process and perceive stimuli towards the contralesional side (opposite side to the stroke) of the body or environment
d) neglect of the body and the external world in the contralateral hemifield
e) patient denies that affected side of body belongs to them

Answer 9

A) Sensoryneglect: incoming sensory information from the contralateral hemispace is ignored
B) Conceptual neglect: neglect of the body and the external world in the contralateral hemifield
C) Hemiasomatognosia: patient denies that affected side of body belongs to them
E) Hemineglect: patient can’t process and perceive stimuli towards the contralesional side (opposite side to the stroke) of the body or environment
D) Motorneglect: fewer movements in the contralateral space
