rare becase its caused by bilateral parietal lesions

Question 2

contralateral neglect

Answer 2

neglect spatial info on the opposite side of your body to the hemi lesioned, typically right parietal lesion caused by stroke

Question 3

do patients with contralateral neglect know there is anything wrong (typically)?

Answer 3

no not usually

Question 4

Answer 4

frontal lobes, congulate cortex, or subcortical regions
due to impaired sensation and perception or attention

Answer 5

the right inferior parietal lobe

Question 6

how might posterior parietal damage affect object recognition

impair ability to recognize objects from unfamiliar angles and trouble mentally rotating objects

Question 7

apraxia

Answer 7

loss of skilled movement

Question 8

ideomotor apraxia

Answer 8

unable to copy movements made by others
associated with left parietal lobe lesions and dorsal stream

Question 9

construction apraxia

Answer 9

issues with spatial organization like doing puzzles, drawing, copying facial movements
associated with damage to posterior parietal lobe in left or right side

Question 10

drawing and left parietal damage

Answer 10

simple and often unrecognizable

Question 11

impair manipulation of the image

Question 16

Answer 16

the left

Question 17
