neuropsych final exam tests 1 and 2 Flashcards
visual processing occurs in the what lobe
occipital
anatomical feature of primary visual cortex
calcarine sulcus
in the superior temporal sulcus, neurons are active in the what
STS
visual cortex has no regions for what
emotion
ventral stream does
visual object recognition
facial features follow visual attention to
L visual field
milner and goodale posterior parietal research
activation when monkey reaches for stimulus
STS has
polysensory
blindness to the entire visual field
homonymous hemianopia
unilateral destucion of L occipital lobe is
Rvisual field hemianopia
most of the primary visual cortex is represented in the
fovea
bitemporal hemianopia
loss of vision from bth temporal fields, lesion to optic chiasm, peripheral vision on both sides lost
nasal hemianopia
loss of vision to 1 nasal field, lesion of lateral chiasm
homonymous hemianopia
blindness of entire visual field, results from complete cut of optic tract, LGN or V1, cut at bottom
macular sparing
sparing of central or macular region of visual field, lesion to occipital lobe
no conscious awareness of touch, but can accurately report it
blindsight
unable to use visual info to guide movement
optic ataxia
apperceptive agnosia
inability to perceive structure of objects, widespread bilateral occipital lobe
prosopagnosia
cant recognize faces
blind spot
scotoma
simultagnosia
inability to see multiple objects at the same time
anosognosia
lack of awareness
acalculia
inability to do calculations
astereogenosis
inability to recognize an object by touch
autopagnosia
no knowledge of issues, no awareness of body
agraphia
cant write
dysphasia
inability to speak, comprehend
afferent paresis
clumsy finger movements
apraxia
nothing is wrong but you lose movement—ideomotor, constructional
associative agnosia
describe, not name
image generation occurs in
L hemisphere
parietal lobe ventrally marked by
sylvian fissure
supramarginal/angular gyrus demarks
inferior parietal
parietal cortex and prefrontal cortex function
spatially guided behavior
posterior parietal damage causes inability to
reach toward visual target
sensory feedback actual outcome intended movement is
efference
medial parietal region function
spatial navigation
mental transformations
organize gray matter in anterior parietal
math, mentally rotating and manipulating objects
mental space in posterior parietal
posterior to central sulcus function
processing somatosensory info
pari stroke-reports R touch when L touch
allesthesia
1 object at a time, misreach–disease
Ballint’s
R parietal lesions-what neglect
unilateral neglect
hemispatial neglect causes
impaired attention to personal space
cant identify fingers/do math
Gerstmann
posterior parietal does what
L and R distinguishing
Posner, parietal lobes to attention
shift attention
R pari
R/L distinguishing
line bisection task
contralateral task
auditory association cortex
insula
anterior commissure connects R&L
medial temp
neurons in the middle temporal gyrus
corpus callosum
hippocampus input
perforant pathway
temporal lobes
control visual tracking
