Cortical Functions Flashcards
What is Balint’s syndrome?
combination of: optic ataxia (visual-guided reaching), optic apraxia (difficulty scanning), and simultanagnosia
caused by: bilateral parietal lesion
damage to the non-dominant inferior temporal lobe would result in:
prosopagnosia
damage to the inferior region and angular gyrus of the temporal cortex in the dominant hemisphere would cause:
acalculia
utilization behavior is attributed to:
frontal lobe damage
perception of ownership for our decisions requires the:
parietal cortex
what is abulia?
inability to initiate movement
when projections from the frontal cortex that normally inform the parietal cortex of imminent actions is impaired, this syndrome can occur:
alien hand syndrome
Communication between the two hemispheres is limited to axons projecting:
across the corpus collosum and anterior commissure
the “dominant” hemisphere refers to which hemisphere controls:
language
Broca’s aphasia is characterized by:
inability to produce speech. comprehension of speech is fine, but only one or two words can be produced
Wernicke’s aphasia, also called ____ ____, is characterized by;
receptive aphasia; inability to decode the meaning of words
What is the wada test?
anesthetic is injected into the internal carotid artery on one side, and the patient is observed to see if language abilities are affected. Determines which hemisphere is dominant.
Areas 44 & 45 are:
Broca’s area
Area 7 & 39is:
Parietal cortex
Area 22 is:
Wernicke’s area
what is contralateral neglect syndrome?
damage to the parietal cortex in the non-dominant hemisphere results in inability to perceive objects in the contralateral field, including in extreme cases the patient’s own body.
parietal cortex receives:
multimodal somatosensory and visual input
temporal cortex receives:
visual and auditory input
the temporal lobe is responsible for:
recognition of objects/faces and language comprehension
