ANSWERS
1. What is the typical frequency range of alpha rhythm in an adult EEG?
A. 4–7 Hz
B. 8–13 Hz
C. 14–30 Hz
D. >30 Hz
Correct Answer: B. 8–13 Hz
Explanation: Alpha rhythm typically occurs at 8–13 Hz, predominantly in the occipital region
when the eyes are closed in a relaxed adult. It attenuates with eye opening.
2. Which of the following waveforms is most commonly seen in sleep stage N2?
A. Vertex waves
B. K-complexes and sleep spindles
C. Slow waves
D. Delta waves
,Correct Answer: B. K-complexes and sleep spindles
Explanation: Stage N2 sleep is characterized by the appearance of sleep spindles (12–14 Hz)
and K-complexes, which are large negative waves followed by a positive component.
3. A 3-Hz spike-and-wave discharge on EEG is classically associated with which
condition?
A. Lennox-Gastaut Syndrome
B. Absence seizures
C. Infantile spasms
D. Focal epilepsy
Correct Answer: B. Absence seizures
Explanation: Typical absence seizures are associated with generalized 3-Hz spike-and-wave
discharges on EEG, often triggered by hyperventilation.
4. What is the most effective way to reduce 60 Hz electrical artifact during an EEG
recording?
A. Increase filter settings
B. Use a notch filter
C. Ask the patient to stay still
D. Decrease the paper speed
Correct Answer: B. Use a notch filter
Explanation: A 60 Hz notch filter is designed to eliminate power line interference that is
common in the US and Canada. This filter attenuates that specific frequency.
5. What electrode placement system is standard in EEG recording?
A. 12-lead system
B. 10–20 International System
C. Modified Lead System
D. 3-Point Cranial System
Correct Answer: B. 10–20 International System
Explanation: The 10–20 system is the universally accepted method for electrode placement in
EEG, ensuring reproducibility and standardization.
6. What is the term for rhythmic, sharply contoured theta activity seen in the temporal
lobe of drowsy adults?
, A. Mu rhythm
B. POSTS
C. Wicket spikes
D. Rhythmic temporal theta bursts of drowsiness (RTTBD)
Correct Answer: D. Rhythmic temporal theta bursts of drowsiness (RTTBD)
Explanation: RTTBD, also known as psychomotor variant, is a benign variant often seen in
drowsy individuals, especially young adults.
7. Which of the following is most suggestive of an epileptogenic focus on an interictal
EEG?
A. Alpha rhythm
B. Sleep spindles
C. Sharp waves
D. Eye blink artifact
Correct Answer: C. Sharp waves
Explanation: Sharp waves, especially when focal or repetitive, are indicative of an
epileptogenic zone and are important in the diagnosis of epilepsy.
8. What condition is typically associated with hypsarrhythmia on EEG?
A. West syndrome
B. Juvenile myoclonic epilepsy
C. Benign rolandic epilepsy
D. Landau-Kleffner syndrome
Correct Answer: A. West syndrome
Explanation: Hypsarrhythmia is a chaotic, high-amplitude, disorganized EEG pattern typically
seen in infantile spasms (West syndrome).
9. A photic driving response is seen during:
A. Hyperventilation
B. Eyes closed
C. Photic stimulation
D. REM sleep
Correct Answer: C. Photic stimulation
Explanation: Photic driving is a normal response characterized by occipital EEG activity
entrained by the frequency of the strobe light during photic stimulation.
