Q

astereognosis

A

inability to perceive object by touch- postcentral gyrus, PE, PF

17
Q

afferent paresis

A

movements of the fingers are clumsy b/c of damage to postcentral gyrus, PE, PF

18
Q

simultaneuous extinction difficulties

A

inability to perceive two identical objects or two similar objects. But can ID two different objects, PE and PF in R. parietal lobe

19
Q

asomatognosia

A

loss of knowledge of one’s own body and bodily condition- lots of subtypes. PE and PF

20
Q

anosognosia

A

unawareness or denial of illness

21
Q

anosodiaphoria

A

indifference to illness- more common in R hemisphere

22
Q

autopagnosia

A

inability to localize body parts, most common is finger agnosia. Lateralized to posterior parietal lobule of L hemisphere

23
Q

gerstmann syndrome

A

finger agnosia, R/L confusion, acaculia, agraphia

L. hemisphere- PF and PG

24
Q

hemispatial neglect

A

unaware of the locations and objects contralateral to brain damage- most often R PPC- spatial attention disorder

25
Q

visual disorientation

A

cant accurately point to locations in space
lesion in occipitotemporoparietal junction
evidence of 2 independent cortical visual systems- object recognition and spatial location

26
Q

constructional apraxia

A 
impaired visuoperception, visually guided action, and executive function
posterior parietal lobe
difference between R and L
R is detail but spatial problems
L  is bad detail

visually guided reach

29
Q

lateral intraparietal area LIP

A

saccadic movements

30
Q

ideomotor apraxia

unable to imitate movements- will substitute some- can do it randomly sometimes but not on cue
left posterior parietal ctx

31
Q

sensory neglect

A

neglect of perceptual input- could be any perception

32
Q

motor neglect

A

neglect of response output- could have trouble maintaning, initiaintng, disenganging etc.

33
Q

neglect areas

A

IPL, 39, 40
DL frontal, cingulate, thalamus, basal ganglia, white matter
IPL is where and what system combine

34
Q

balints syndrome

A

simultagnosia, optic ataxia, psychic paralysis of gaze

bilateral lesions of PPL and occipital lobes
