Question #1
Like the sensory systems, the sensorimotor system is
A.
hierarchical.
B.
all of these
C.
parallel
D.
functionally segregated.
Question #2
Which kinds of movements are NOT influenced by sensory feedback?
A.
innate movements
B.
ballistic movements
C.
reflexive movements
D.
unpracticed movements
E.
practiced movements
Question #3
With respect to sensorimotor learning, the advantage of transferring control to lower circuits of the neural hierarchy is that it
A.
increases conscious awareness of the response.
B.
all of these
C.
frees the higher levels of the nervous system to deal with more complex issues.
D.
increases the reliability of movements.
E.
increases validity.
Question #4
During sensorimotor learning,
A.
the locus of control is often shifted from conscious to unconscious control mechanisms
B.
the locus of control is often shifted to lower levels of the sensorimotor hierarchy.
C.
all of these
D.
individual responses are often integrated into continuous motor programs.
Question #5
Much of the output of the posterior parietal cortex goes to the
A.
all of these
B.
various areas of secondary motor cortex.
C.
frontal eye fields.
D.
dorsolateral prefrontal association cortex.
Question #6
Apraxia typically affects
A.
only the left side of the body.
B.
only the arms.
C.
only the right side of the body.
D.
only the legs.
E.
both sides of the body.
Question #7
In general, the various areas of secondary motor cortex are thought to
A.
terminate response sequences.
B.
program specific patterns of movement.
C.
provide the major input to spinal motor circuits.
D.
specialize in guiding learned sequences.
E.
mediate reflexes.
Question #8
Neurons that fire in response to making a particular response, observing somebody else making the response, or just thinking about the response are called
A.
mirror neurons.
B.
ballistic neurons.
C.
supplementary motor neurons.
D.
somatotopic neurons.
E.
premotor neurons.
Question #9
In 1937, the primary motor cortex was mapped by electrically stimulating the cortex of conscious human patients who were undergoing neurosurgery. This was accomplished by

stereognosis.
B.
somatotopic homunculus.
C.
motor homunculus.
D.
supplementary map.
E.
somatosensory homunculus.
Question #11
The primary motor cortex receives cutaneous feedback from only one part of the body: the hands. This feedback likely plays an important role in
A.
the cingulate motor areas.
B.
astereognosia.
C.
stereognosis.
D.
apraxia.
E.
the homunculus.
Question #12
In a remarkable demonstration, Belle, the owl monkey, controlled the movements of a robotic arm
A.
with monkey calls.
B.
with speech sounds.
C.
by pressing buttons.
D.
by providing visual feedback to the arm.
E.
with the activity of neurons in her primary motor cortex.

A deficit in the ability to recognize objects by touch is called
A.
asomatognosia.
B.
apraxia.
C.
astereognosia.
D.
homunculus.
E.
stereognosis.

A.
corpus callosum.
B.
hippocampus.
C.
cerebellum.
D.
brain stem.
