Chapter 1 — Structure and Function: Neuroanatomy and Research Methods
Question 1
A neuroimaging research team compares activity across several brain regions while participants complete a
spatial-navigation task. The following results are recorded:
Brain Region Relative Activity During Task
Hippocampus +68%
Primary motor cortex +12%
Medulla +4%
Primary auditory cortex +7%
Which interpretation is most strongly supported by these findings?
A. The hippocampus is associated with processing demands required by the spatial-navigation task.
B. The medulla is the primary neural structure responsible for spatial memory.
C. Motor-cortex activity proves that movement is necessary for hippocampal activation.
D. Auditory processing is the dominant cognitive requirement of the task.
,Correct Answer: A. The hippocampus is associated with processing demands required by the spatial-
navigation task.
Rationale:
The hippocampus plays a major role in spatial memory, navigation, and the formation of relational memories.
The large increase in hippocampal activity compared with the other regions therefore supports an association
between hippocampal processing and successful spatial-navigation performance. However, functional
activation alone does not establish that the hippocampus is solely responsible for the behavior or that its
activation is causally necessary.
Why the other options are less appropriate:
B. The medulla primarily regulates vital autonomic functions rather than spatial-memory processing.
C. Increased motor-cortex activity does not demonstrate that motor activity causes hippocampal activation.
D. Primary auditory cortex shows only a small activity increase and is primarily involved in auditory processing.
Neuroscience Pearl:
The hippocampus is especially important for spatial representation and declarative memory, while functional
imaging demonstrates association rather than automatic proof of causation.
Exam Strategy:
When a question presents a brain-activity table, identify the region showing the strongest task-related change
and connect it with its established function. Avoid options that turn correlation into causation.

Damage selectively removes the insulating segments shown around the axon while leaving the neuronal cell
body intact. Which functional consequence is most likely?
A. Increased synthesis of neurotransmitter in the soma
B. Slower and less efficient propagation of action potentials
C. Complete elimination of dendritic synaptic input
D. Increased speed of chemical transmission across every synapse
Correct Answer: B. Slower and less efficient propagation of action potentials.
Rationale:
Myelin electrically insulates axons and allows action potentials to propagate rapidly through saltatory
conduction, in which depolarization is regenerated primarily at the nodes of Ranvier. Loss of myelin decreases
conduction efficiency and may cause substantial slowing or failure of signal transmission.
Why the other options are less appropriate:
A. Myelin loss does not directly increase neurotransmitter synthesis in the soma.
C. Dendritic synapses can remain anatomically intact despite demyelination.
D. Myelin primarily influences electrical conduction along the axon, not the speed of neurotransmitter
diffusion across synaptic clefts.
Neuroscience Pearl:
In the CNS, oligodendrocytes form myelin; in the PNS, Schwann cells form myelin. This distinction is
frequently tested.
Exam Strategy:
Whenever a stem mentions myelin, nodes of Ranvier, or demyelination, immediately think about conduction
velocity and saltatory conduction before considering synaptic or neurotransmitter effects.
Question 3
During experimental planning, four research methods are proposed for determining whether a specific
cortical area is necessary for visual discrimination.
Proposed Method Primary Measurement
Method 1 Correlation between cortical thickness and test scores
Method 2 Functional MRI activity during visual discrimination
Method 3 Temporary disruption of the cortical area followed by performance testing
,Proposed Method Primary Measurement
Method 4 Participant questionnaire about perceived difficulty
Which method provides the strongest evidence for a causal contribution of the cortical region to visual
discrimination?
A. Method 1
B. Method 2
C. Method 3
D. Method 4
Correct Answer: C. Method 3.
Rationale:
Experimentally disrupting the activity of a specific brain region and then measuring whether behavior changes
provides much stronger evidence for causal involvement than merely observing correlations or activity. If
disruption selectively worsens visual discrimination under controlled conditions, investigators can reasonably
infer that the targeted area contributes to the behavior.
Why the other options are less appropriate:
A. Structural correlations cannot establish causality.
B. fMRI demonstrates task-related activity but does not by itself establish that the region is necessary.
D. Subjective reports do not directly test neural causation.
Neuroscience Pearl:
A region can become active during a task without being strictly necessary for that task. Lesion and temporary-
inactivation approaches can therefore complement functional imaging.
Exam Strategy:
For research-method questions, distinguish association from causation. Experimental manipulation with an
appropriate behavioral outcome generally provides stronger causal evidence than correlation alone.
Question 4
Emergency neurological assessment identifies a small brainstem hemorrhage. The examination findings are
summarized below:
Assessment Element Finding
Consciousness Drowsy but arousable
Respiratory pattern Irregular and progressively slowing
Blood pressure Markedly unstable
,Assessment Element Finding
Pupillary response Present
Limb strength Mild bilateral weakness
Which anatomical interpretation best accounts for the findings that create the greatest immediate threat to
survival?
A. Damage to occipital cortical circuits controlling visual perception
B. Injury to hippocampal networks responsible for memory consolidation
C. Disruption of medullary circuits regulating respiration and cardiovascular function
D. Damage to basal ganglia circuits responsible for voluntary movement selection
Correct Answer: C. Disruption of medullary circuits regulating respiration and cardiovascular function
Rationale:
The medulla is part of the hindbrain and contains neural circuitry essential for respiratory rhythm,
cardiovascular regulation, and several protective reflexes. Progressive respiratory irregularity together with
cardiovascular instability therefore strongly suggests disruption of medullary function. Because these
processes are essential for maintaining life, medullary damage represents a much more immediate
physiological threat than dysfunction involving higher-order cognitive or sensory regions.
Why the other options are less appropriate:
A. Occipital damage would primarily impair visual processing rather than directly destabilize breathing and
blood pressure.
B. Hippocampal injury would predominantly affect learning and memory.
D. Basal ganglia injury can produce severe motor abnormalities but does not ordinarily produce the
combination of respiratory and cardiovascular instability shown here.
Neuroscience Pearl:
The medulla, pons, and midbrain form the brainstem, but the medulla is especially important for basic
autonomic functions necessary for survival.
Exam Strategy:
When several neurological findings are presented, identify the one involving a vital physiological function.
Respiratory and cardiovascular abnormalities should immediately direct attention toward the brainstem,
particularly the medulla.
Question 5
Microscopic examination of central nervous system tissue reveals the following cellular profiles:
Cell Population Observed Characteristic
Cell W Forms insulating membranes around several axons
,Cell Population Observed Characteristic
Cell X Removes cellular debris after neural injury
Cell Y Regulates extracellular ions and supports neurons metabolically
Cell Z Lines fluid-filled ventricular spaces
Which pairing correctly identifies Cell W and Cell X?
A. Schwann cell and astrocyte
B. Oligodendrocyte and microglial cell
C. Astrocyte and ependymal cell
D. Ependymal cell and oligodendrocyte
Correct Answer: B. Oligodendrocyte and microglial cell
Rationale:
Oligodendrocytes produce myelin in the central nervous system and may myelinate segments of several
different axons. Microglia serve immune-surveillance and phagocytic functions and become especially active
following injury or infection. The descriptions of Cell W and Cell X therefore correspond most precisely to
oligodendrocytes and microglia, respectively.
Why the other options are less appropriate:
A. Schwann cells myelinate peripheral rather than central nervous system axons, while astrocytes are not the
major phagocytic immune cells of the CNS.
C. Astrocytes contribute metabolic and homeostatic support, whereas ependymal cells line ventricular spaces.
D. Ependymal cells do not normally provide axonal myelin, and oligodendrocytes are not the principal
phagocytic cells.
Neuroscience Pearl:
A high-yield glial distinction is: oligodendrocytes = CNS myelin, Schwann cells = PNS myelin, microglia =
immune defense, astrocytes = neural support/homeostasis.
Exam Strategy:
For glial-cell questions, match the function first and the cell name second. Myelin location—CNS versus PNS—
is often the decisive clue.
Question 6
Before beginning a study of language processing, investigators compare four possible research designs:
Design Procedure
I Measure language scores and correlate them with cortical thickness
,Design Procedure
II Record fMRI activity while participants perform a language task
III Temporarily disrupt a targeted cortical region and measure resulting language performance
IV Ask participants which brain region they believe is most active
Which design provides the strongest evidence that the targeted cortical region is necessary for the behavior?
A. Design I
B. Design II
C. Design III
D. Design IV
Correct Answer: C. Design III
Rationale:
Temporary disruption directly manipulates activity in the proposed neural substrate and then evaluates
whether behavioral performance changes. This experimental approach provides substantially stronger
evidence of causal necessity than correlational anatomy or task-associated activation. If selective disruption
reliably produces an impairment while relevant controls are maintained, the targeted area can be inferred to
contribute causally to normal performance.
Why the other options are less appropriate:
A. Correlation between anatomy and performance establishes association, not causality.
B. fMRI reveals task-associated changes in blood oxygenation but does not prove that the activated area is
necessary.
D. Participant beliefs provide subjective information and no direct neural evidence.
Neuroscience Pearl:
Neuroscience often combines correlational methods such as imaging with causal methods such as lesions,
stimulation, or temporary inactivation.
Exam Strategy:
Watch for wording such as “necessary,” “causes,” or “causal contribution.” These terms favor an experimental
manipulation over a simple correlation.
Question 7
A midsagittal brain sketch labels four structures involved in communication, homeostasis, sensory relay, and
movement coordination:
Cerebral Cortex
___________________

| _______ |
| / \ |

\_______________________\
Label A represents the major fiber tract connecting the two cerebral hemispheres. Which structure should
be assigned to A?
A. Corpus callosum
B. Hypothalamus
C. Cerebellum
D. Medulla
Correct Answer: A. Corpus callosum
Rationale:
The corpus callosum is a massive bundle of commissural axons connecting the left and right cerebral
hemispheres. It permits extensive interhemispheric transfer of sensory, motor, and cognitive information. Its
characteristic location near the midline makes it particularly prominent in midsagittal brain sections.
Why the other options are less appropriate:
B. The hypothalamus lies beneath the thalamic region and plays major homeostatic and endocrine roles.
C. The cerebellum occupies the posterior hindbrain and contributes to coordinated movement.
D. The medulla is part of the caudal brainstem.
Neuroscience Pearl:
A commissure is a tract crossing the midline to connect corresponding or related regions on opposite sides of
the nervous system.
Exam Strategy:
On sagittal neuroanatomy images, look first for relative position and function. A large midline tract linking
hemispheres almost always points to the corpus callosum.
Question 8
Behavioral testing after a focal neurological injury produces the following pattern:
