Question #1
Like the sensory systems, the sensorimotor system is
A.
functionally segregated.
B.
all of these
C.
parallel
D.
hierarchical.
Question #2
Which kinds of movements are NOT influenced by sensory feedback?
A.
practiced movements
B.
reflexive movements
C.
innate movements
D.
ballistic movements
E.
unpracticed 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 the reliability of movements.
B.
frees the higher levels of the nervous system to deal with more complex issues.
C.
increases conscious awareness of the response.
D.
all of these
E.
increases validity.
Question #4
During sensorimotor learning,
A.
the locus of control is often shifted from conscious to unconscious control mechanisms
B.
all of these
C.
individual responses are often integrated into continuous motor programs.
D.
the locus of control is often shifted to lower levels of the sensorimotor hierarchy.
Question #5
Much of the output of the posterior parietal cortex goes to the
A.
various areas of secondary motor cortex.
B.
frontal eye fields.
C.
all of these
D.
dorsolateral prefrontal association cortex.
Question #6
Apraxia typically affects
A.
only the legs.
B.
only the left side of the body.
C.
only the arms.
D.
both sides of the body.
E.
only the right side of the body.
Question #7
In general, the various areas of secondary motor cortex are thought to
A.
program specific patterns of movement.
B.
provide the major input to spinal motor circuits.
C.
mediate reflexes.
D.
terminate response sequences.
E.
specialize in guiding learned sequences.
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.
premotor neurons.
B.
somatotopic neurons.
C.
mirror neurons.
D.
supplementary motor neurons.
E.
ballistic 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
A.
Pinel.
B.
Sperry.
C.
Jackson.
D.
Hebb.
E.
Penfield and Boldrey.
Question #10
The somatotopic map of the primary motor cortex is called the
A.
motor homunculus.
B.
stereognosis.
C.
somatosensory homunculus.
D.
somatotopic homunculus.
E.
supplementary map.
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.
stereognosis.
B.
the cingulate motor areas.
C.
astereognosia.
D.
apraxia.
E.
the homunculus.
Question #12
In a remarkable demonstration, Belle, the owl monkey, controlled the movements of a robotic arm
A.
by pressing buttons.
B.
with the activity of neurons in her primary motor cortex.
C.
with speech sounds.
D.
by providing visual feedback to the arm.
E.
with monkey calls.
Question #13
A deficit in the ability to recognize objects by touch is called
A.
apraxia.
B.
astereognosia.
C.
stereognosis.
D.
homunculus.
E.
asomatognosia.

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

A.
cerebellum
B.
red nucleus
C.
substantia nigra
D.
reticular formation
E.

Question #16
Signals from the left primary motor cortex descend through the spinal cord white matter in one of
A.
four major tracts.
B.
eight major tracts.
C.

A.
motor neurons that project to the muscles of the fingers and thumb.
B.
muscles.
C.
spinal interneurons.
