Both of Broca's patients had a left-hemisphere lesion that involved an area in the _____ cortex.
A.
temporal
B.
occipital
C.
frontal
D.
parietal - =C
The sodium amytal test involves the injection of a small amount of sodium amytal into the
carotid artery on one side of the neck. This injection:
A.
puts the patient to sleep.
B.
always impairs language production.
C.
anesthetizes the hemisphere on the opposite side for a few minutes.
D.
anesthetizes the hemisphere on that side for a few minutes. - =D
During one trial of a patient's dichotic listening test, "5," "9," and "6" are presented to the right
ear, and "2," "4," and "7" are presented to the left ear. The patient reports hearing "5," "9," "6,"
and "2." The patient's response suggests that the neural regulation of their language abilities is:
A.
lateralized to the left hemisphere.
B.
lateralized to the right hemisphere.
,C.
nondominant.
D.
left recessive. - =A
The left hemisphere is dominant for language-related abilities in ______ dextrals and in _____
sinestrals.
A.
the majority of; a minority of
B.
almost all; almost all
C.
the majority of; few if any
D.
almost all; the majority of - =A
The popular notion that male brains are more strongly lateralized than female brains is supported
by:
A.
the effects of unilateral strokes in men and the the the results of functional brain-imaging studies,
but not the effects of unilateral strokes in men and women.
B.
neither the effects of unilateral strokes in men and women, nor the results of functional brain-
imaging studies.
C.
both the effects of unilateral strokes in men and women, and the results of functional brain-
imaging studies.
D.
the effects of unilateral strokes in men and women, but not the results of functional brain-
imaging studies. - =B
, Because there are two routes by which visual information can cross from one eye to the
contralateral hemisphere, Myers and Sperry transected both the ____________ and the
_______________ of each cat in their key experimental group.
A.
optic nerve; optic chiasm
B.
corpus callosum; lateral habenulum
C.
optic chiasm; corpus callosum
D.
optic chiasm; fornix - =C
Like split-brain laboratory animals, human split-brain patients seem to have
__________________. But unlike the hemispheres of split-brain laboratory animals, the
hemispheres of split-brain patients are ______________ in their ability to perform certain tasks.
A.
two independent brains; unequal
B.
one brain; unequal
C.
only one optic tectum; disturbed
D.
two independent brains; equal - =A
Although the two hemispheres of a split-brain patient have no means of direct neural
communication, they can communicate neurally via indirect pathways through the
_______________. They can also communicate with each other by an external route, by a
process called _______________.
A.
brain stem; cross-cuing
