B. Subdural space located beneath dura mater
C. Subarachnoid space surrounding the brain
D. Central canal passing through spinal cord
Answer: C
Rationale: CSF exits the fourth ventricle through the apertures of Luschka and Magendie into the
subarachnoid space (between the arachnoid mater and pia mater), where it cushions the brain and is
reabsorbed via arachnoid villi into dural venous sinuses.
Question 8
Topic: Neuronal Functional Zones and Signal Integration
Bloom's Level: Remember/Understand
Which structural region of the neuron acts as the integration zone where incoming synaptic
potentials are summed to determine whether an action potential will be initiated?
A. Dendritic spine arborizations
B. Axon hillock initial segment
C. Synaptic axon terminal boutons
D. Unmyelinated nodes of Ranvier
Answer: B
Rationale: The axon hillock and adjacent initial segment have a high density of voltage-gated sodium
channels and integrate postsynaptic potentials (EPSPs and IPSPs) to determine if threshold is reached.
Question 9
Topic: Glial Cells and Myelination in CNS vs. PNS
Bloom's Level: Remember/Understand
,In the central nervous system, which type of glial cell wraps around axons to form myelin
sheaths, and what is its counterpart in the peripheral nervous system?
A. Microglia within CNS; Schwann cells in PNS
B. Astrocytes within CNS; oligodendrocytes in PNS
C. Oligodendrocytes in CNS; Schwann cells in PNS
D. Schwann cells within CNS; astrocytes in PNS
Answer: C
Rationale: Oligodendrocytes form myelin sheaths around multiple axon segments in the CNS, whereas
Schwann cells provide myelination for single axon segments in the PNS.
Question 10
Topic: Microglial Activation in Brain Injury
Bloom's Level: Remember/Understand
Following a focal ischemic stroke, which glial cell type becomes activated, alters its morphology
to act as a phagocyte, and clears cellular debris from the damaged tissue site?
A. Resident microglial glial cells
B. Myelinating oligodendrocyte cells
C. Neurogenic radial glial line cells
D. Ventricular ependymal lining cells
Answer: A
Rationale: Microglia are the resident immune cells of the CNS; upon injury, they transform into active
phagocytes to engulf necrotic debris and cellular pathogens.
Question 11
Topic: Functional Neuroimaging (fMRI)
Bloom's Level: Apply/Analyze
A researcher wants to measure changes in oxygenated blood flow in human participants in real
time while they perform a language task. Which imaging technique is best suited for this study
due to its non-invasive nature and good spatial resolution?
A. Computed Tomography scanning with radiological contrast
B. Functional Magnetic Resonance Imaging technique (fMRI)
, C. Positron Emission Tomography using radioactive glucose
D. Scalp Electroencephalography recording methods (EEG)
Answer: B
Rationale: fMRI detects changes in blood oxygenation level-dependent (BOLD) signals, providing high
spatial resolution of active neural regions without exposing participants to ionizing radiation.
Question 12
Topic: Electrophysiological Recording Methods (EEG)
Bloom's Level: Apply/Analyze
An investigator studying epilepsy needs to record electrical activity of the cerebral cortex with
millisecond temporal resolution to pinpoint the precise onset of seizure spikes. Which method
should be selected?
A. Structural Magnetic Resonance Imaging methods scan
B. Positron Emission Tomography scanning methods
C. Scalp Electroencephalography recording methods

populations, providing millisecond-level temporal resolution ideal for detecting rapid electrophysiological
events like seizure spikes.
Question 13
Topic: Causal Inference in Behavioral Neuroscience (Necessity vs. Sufficiency)
Bloom's Level: Evaluate/Synthesize
If electrical stimulation of the amygdala elicits defensive freezing and autonomic arousal in an
awake animal, whereas bilateral lesion of the same structure abolishes fear responses to
conditioned stimuli, what can be inferred about the amygdala's role?
A. Amygdala activity is sufficient without being strictly required for fear expression. B.
Amygdala activity plays a predominantly inhibitory role in emotional processing.
C. Amygdala activity represents an indirect non-causal byproduct of motor activation.
D. Amygdala activity is both necessary and sufficient for mediating fear responses.
,Answer: D
Rationale: Stimulation inducing the behavior demonstrates sufficiency, while lesioning eliminating the
behavior demonstrates necessity, establishing that the amygdala is both necessary and sufficient for fear
processing.
Question 14
Topic: Experimental Design and Correlational Limitations
Bloom's Level: Evaluate/Synthesize
A study finds a strong positive correlation between cortical thickness in the hippocampus and
spatial memory performance in older adults. What limits researchers from establishing that
increased hippocampal thickness directly causes better spatial memory?
A. Correlational observational designs inherently lack longitudinal follow-up measurements across
aging cohorts.
B. Third variables or reverse causality cannot be ruled out without experimental manipulation of the
variable.
C. Cortical thickness metrics cannot be quantified with sufficient accuracy using structural MRI
neuroimaging.
D. Spatial memory tasks primarily evaluate subcortical brain function rather than cerebral cortical
integrity.
Answer: B
Rationale: Correlational designs demonstrate association between variables but cannot establish
causality, as unmeasured confounding variables or bidirectional influences may account for the
relationship.
Question 15
Topic: Optogenetics vs. Electrical Stimulation
Bloom's Level: Apply/Analyze
A neuroscientist uses optogenetics to selectively express channelrhodopsin-2 in
parvalbuminpositive interneurons of the medial prefrontal cortex. What unique advantage does
this technique offer over traditional electrical stimulation?
A. It substantially eliminates the requirement for invasive cranial surgery or implantation of optical fibers.
, B. It visualizes systemic metabolic turnover of neurotransmitter precursors dynamically across the whole
brain.
