TBL2 Flashcards
damage to parietal cortex can lead to
neglect- inability to perceive objects in environment
contralateral neglect syndrome
damage to non-dom parietal lobe causes you to not be able to perceive stuff in opposite lobe
extinction
when you cant see the contralateral stimuli when you see symmetrical stimuli
optic apraxia
deficits in visual scanning of environemnt
optic ataxia
deficits in hand eye coordination
simultangnosia
inability to preceive multiple objects in visual field after bilateral damage
Balint’s Syndrome
optic apraxia
optic ataxia
simultangosia
tactile agnosia/astereognosia
inability to idntify objects by touch despite normal sensory ability
*this is because it requires integration of visual and somatosensory which normally occurs in parietal
visual agnosia
inability to recognize objects by sight
prospagnosia
inability to recognize faces (esp in non dom lesions)
auditory agnosia
inability to recognize or make sense of complex sounds (such as words)
receptive aphasia
damage to wernicke’s area–deficits in language comprehension
acalculia
dominant temporal (incl inferiro region and angular gyrus) --impaired arithmitic
anterior cingulate gyrus
esp depression and mania
key role of prefrontal cortex
inhibit motor behavior
utilization behaviors
can no longer inhibit behavior
–individuals grasp nearby objects in purposeful ways, but at inappropriate times
perservation
repetition of a normal motor patter after it should stop
perception of ownership
parietal
decisions themselves
supplementary motor cortex
abulia
inability to initiate movement
stimulate supp motor cortex
urge to move
stimulate parietal
think you moved but didnt
alien hand syndrome
frontal lobe damage
purposeful and coordinated movements of hand without sense of agency
wernicke’s
receptive aphasia- probelms decoding meanings of words
