,Section I: Clinical Case Evaluation & Core Neuroanatomy (Q1 -
Q40)
Q1. A 55-year-old female with treatment-refractory major depressive
disorder (TRD) is being evaluated for Transcranial Magnetic
Stimulation (TMS). What is the primary anatomical brain region
targeted during standard high-frequency rTMS protocols for depression?
A) Left Dorsolateral Prefrontal Cortex (DLPFC)
B) Right Dorsolateral Prefrontal Cortex (DLPFC)
C) Subgenual Anterior Cingulate Cortex (sgACC)
D) Left Ventromedial Prefrontal Cortex (VMPFC)
Correct Answer: A
Rationale: Standard FDA-cleared high-frequency rTMS protocols
for depression target the left dorsolateral prefrontal cortex (DLPFC,
Brodmann area 9/46). The left DLPFC is hypoactive in depression
and has direct and indirect monosynaptic/polysynaptic connections to
limbic structures such as the amygdala and subgenual anterior
cingulate cortex (sgACC).
Q2. In the context of the 55-year-old female patient evaluated for TMS,
treatment-refractory depression is most commonly defined after failing
how many adequate trials of distinct antidepressant medications?
A) One trial
B) Two trials
C) Four trials
D) Six trials
Correct Answer: B
Rationale: Treatment-resistant depression (TRD) in clinical trials
and clinical practice guidelines (such as the STAR*D trial and FDA
TMS indications) is standardly defined as an inadequate clinical
, response to at least two distinct antidepressant trials of adequate
dose and duration.
Q3. When localizing the left DLPFC using the standard 'BeamF3'
method, which three scalp landmarks measured via the international 10-
20 EEG system are primarily utilized?
A) Fp1, Fp2, and Cz
B) Nasion, Inion, and Pre-auricular points (Nz, Iz, T3/T4)
C) F3, C3, and F7
D) Cz, C3, and P3
Correct Answer: B
Rationale: The BeamF3 method utilizes the patient's head
measurements between the nasion, inion, and right/left pre-auricular
points to calculate the precise coordinates corresponding to the F3
electrode position (left DLPFC) using MRI-derived transformation
algorithms.
Q4. What is the underlying physiological mechanism of high-frequency
(e.g., 10 Hz) rTMS applied over the left DLPFC?
A) Long-term depression (LTD) resulting in permanent synaptic
pruning
B) Long-term potentiation (LTP)-like neuroplasticity increasing
cortical excitability and metabolic activity
C) Direct axonal ablation of superficial cortical layers
D) Immediate depletion of synaptic neurotransmitters
Correct Answer: B
Rationale: High-frequency rTMS (>= 5 Hz) induces long-term
potentiation (LTP)-like changes, enhancing excitatory glutamatergic
neurotransmission, increasing local cerebral blood flow, and
, upregulating metabolic activity in the targeted hypoactive left
DLPFC.
Q5. Which neuroimaging technique is most frequently integrated into
modern neuronavigated TMS systems to ensure precise coil placement
relative to the patient's individual gyral anatomy?
A) Functional MRI (fMRI) at rest or structural T1-weighted MRI
B) Single Photon Emission Computed Tomography (SPECT)
C) Routine non-contrast head CT
D) Skull X-ray
Correct Answer: A
Rationale: Structural T1-weighted magnetic resonance imaging
(MRI) scans are coregistered with the patient's head in
neuronavigated TMS systems. This allows real-time tracking of the
magnetic coil relative to the patient's specific cortical anatomy.
Q6. Clinical case analysis (Item 6): What is the primary purpose of
determining the Resting Motor Threshold (RMT) prior to initiating a
TMS treatment course?
A) To calibrate the magnetic stimulus intensity relative to individual
corticospinal excitability
B) To measure the patient's seizure threshold directly
C) To test cranial nerve VII integrity
D) To evaluate peripheral nerve conduction velocity
Correct Answer: A
Rationale: RMT establishes the baseline excitability of the motor
cortex, serving as the universal biological anchor (e.g., 120% RMT)
for therapeutic dosing in the prefrontal cortex.
