, EEG Exam Prep 2026/2027: 180 Practice Questions & Answers
SECTION A: NEUROANATOMY AND PHYSIOLOGY
Question 1
The central sulcus forms the anterior boundary of which anatomical structure?
A. Frontal lobe
B. Occipital lobe
C. Parietal lobe
D. Temporal lobe
Answer: C. Parietal lobe
Explanation: The central sulcus, also known as the fissure of Rolando, separates the frontal
and parietal lobes. The postcentral gyrus, which lies immediately posterior to the central
sulcus, is located within the parietal lobe and contains the primary somatosensory cortex.
Question 2
Broca's area is located in which region of the brain?
A. Superior temporal gyrus
B. Posterior part of the inferior frontal gyrus
C. Angular gyrus
D. Precentral gyrus
Answer: B. Posterior part of the inferior frontal gyrus
Explanation: Broca's area, responsible for speech production and language processing, is
situated in the posterior portion of the inferior frontal gyrus, typically in the dominant
(usually left) hemisphere. Damage to this region results in expressive aphasia.
Question 3
A patient presenting with right hemiparesis most likely has a lesion affecting which area?
A. Right frontal lobe
B. Left frontal lobe
C. Right temporal lobe
D. Left occipital lobe
Answer: B. Left frontal lobe
,Explanation: The motor cortex, located in the precentral gyrus of the frontal lobe, exhibits
contralateral control. A lesion in the left frontal lobe would affect motor function on the right
side of the body, resulting in right hemiparesis.
Question 4
The FT9/T1 and FT10/T2 electrode positions record electrical activity from which region?
A. Posterior temporal lobe
B. Anterior temporal lobe
C. Mid-temporal lobe
D. Occipital lobe
Answer: B. Anterior temporal lobe
Explanation: The FT9/T1 and FT10/T2 electrodes are placed according to the International
10-20 System to record from the anterior temporal lobe. These positions are particularly
valuable for detecting temporal lobe epileptiform activity.
Question 5
Uncal lesions may result in which clinical manifestation?
A. Visual hallucinations
B. Auditory hallucinations
C. Olfactory hallucinations
D. Tactile hallucinations
Answer: C. Olfactory hallucinations
Explanation: The uncus, located in the medial temporal lobe, contains the primary olfactory
cortex. Lesions in this region can produce olfactory hallucinations (uncinate fits), which are
characteristic of temporal lobe epilepsy and certain space-occupying lesions.
SECTION B: EEG FUNDAMENTALS AND INSTRUMENTATION
Question 6
Which type of electrical current flows consistently in one direction only?
A. Alternating current
B. Direct current
C. Pulsating current
D. Rectified current
, Answer: B. Direct current
Explanation: Direct current (DC) provides a steady, unidirectional flow of electrical charge.
In EEG instrumentation, DC amplifiers are used for certain specialized applications, though
most clinical EEG uses AC amplification with specific filter settings.
Question 7
Impedance in EEG recording is best defined as:
A. Resistance to direct current
B. Resistance to alternating current
C. Opposition to voltage flow
D. Measurement of current leakage
Answer: B. Resistance to alternating current
Explanation: Impedance represents the total opposition to alternating current flow,
combining resistance, capacitance, and inductance. In EEG recordings, balanced impedances
are crucial for optimal common mode rejection and artifact reduction.
Question 8
Ohm's Law most directly relates which electrical parameters?
A. Frequency and amplitude
B. Voltage, current, and resistance
C. Power and energy
D. Capacitance and inductance
Answer: B. Voltage, current, and resistance
Explanation: Ohm's Law establishes the fundamental relationship V = IR (Voltage = Current
× Resistance). This principle is essential for understanding EEG signal measurement,
electrode impedance requirements, and amplifier design.
Question 9
The balanced impedance of EEG electrodes is important primarily to:
A. Increase signal amplitude
B. Reduce 60 Hz interference
C. Improve frequency response
D. Decrease recording time
