EEG BOARD PRACTICE EXAM 2026
QUESTIONS AND ANSWERS
CERTIFICATION EVALUATION SET
●● Beta.
Answer: ->14 HZ
-detected during wakefulness, enhanced during drowsiness, and
decreased in deeper sleep
-seen on barbiturates and benzodiazepines
●● Lambda waves.
Answer: -NORMAL, awake
-sharp waves occurring in occipital region (o1/o2) during wakefulness
-visually scanning a picture in a lit room
-physiological, eyes OPEN
-saccadic eye movement
-4-6hz
●● Small sharp spikes / BETS.
Answer: -occurs in stage 1/stage 2
-peaks at 30-60 years
-temporal region
,-occurs sporadically and short duration
-NORMAL benign variant
●● Wicket Spikes.
Answer: -Single spike or 6-11 hz Mu like shape seen in drowsiness and
light sleep.
-mid temporal region
-seen in adults over 30
-NORMAL benign variant
●● 14&6hz positive spikes.
Answer: -posterior/temporal region (t5/t6)
-normal benign variant
-light sleep
-best seen in referential montage
-runs last less than 2 seconds
-seen in a lot of adolescents
●● sleep spindles.
Answer: -11-14hz , 1/2 second duration
-central regions
-asynchrony is abnormal after 2years old
, -stage 2 sleep
●● Hypnagogic Hypersynchrony.
Answer: -2-6years old
-central/frontal regions
-paroxysmal bursts high voltage, 3-4.5hz
-normal variant of drowsiness
●● Dilantin toxicity.
Answer: ataxia (loss of control of body muscles)
●● Laplacian montage.
Answer: -source reference deviation
-looks at only the electrodes that are closest to the point of interest
-emphasizes localized waveforms
●● deja vu.
Answer: -complex partial sz
-automatisms/impaired consciousness
●● extreme spindles.
Answer: -found in MR (mental retardation) patients
