caused by: bilateral parietal lesion

Question 2

damage to the non-dominant inferior temporal lobe would result in:

Answer 2

Question 3

damage to the inferior region and angular gyrus of the temporal cortex in the dominant hemisphere would cause:

Answer 3

acalculia

Question 4

utilization behavior is attributed to:

Answer 4

frontal lobe damage

Question 5

perception of ownership for our decisions requires the:

Answer 7

alien hand syndrome

Question 8

Communication between the two hemispheres is limited to axons projecting:

Answer 8

across the corpus collosum and anterior commissure

Question 9

the “dominant” hemisphere refers to which hemisphere controls:

Answer 9

language

Question 10

Broca’s aphasia is characterized by:

Answer 10

inability to produce speech. comprehension of speech is fine, but only one or two words can be produced

Question 11

Wernicke’s aphasia, also called ____ ____, is characterized by;

receptive aphasia; inability to decode the meaning of words

Question 12

What is the wada test?

Answer 12

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.

what is contralateral neglect syndrome?

Answer 16

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.

temporal cortex receives:

Answer 18

visual and auditory input

Question 19

the temporal lobe is responsible for:
