EEG Board Exam (2026 Edition) | Full Practice
Questions with Confirmed Answers | 100%
Accurate | Grade A+
‣ Mu Rhythm ✓✓-c3/c4 region
-7-11Hz
-does not block with eye opening
-easy to see with eyes open
-blocks unilaterally with contralateral hand
-asymmetrical and asynchronous
-NORMAL
‣ Beta ✓✓->14 HZ
-detected during wakefulness, enhanced during drowsiness, and
decreased in deeper sleep
-seen on barbiturates and benzodiazepines
‣ Lambda waves ✓✓-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 ✓✓-occurs in stage 1/stage 2
-peaks at 30-60 years
-temporal region
-occurs sporadically and short duration
-NORMAL benign variant
‣ Wicket Spikes ✓✓-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 ✓✓-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 ✓✓-11-14hz , 1/2 second duration
-central regions
-asynchrony is abnormal after 2years old
, -stage 2 sleep
‣ Hypnagogic Hypersynchrony ✓✓-2-6years old
-central/frontal regions
-paroxysmal bursts high voltage, 3-4.5hz
-normal variant of drowsiness
‣ Dilantin toxicity ✓✓ataxia (loss of control of body muscles)
‣ Laplacian montage ✓✓-source reference deviation
-looks at only the electrodes that are closest to the point of interest
-emphasizes localized waveforms
‣ deja vu ✓✓-complex partial sz
-automatisms/impaired consciousness
‣ extreme spindles ✓✓-found in MR (mental retardation) patients
-high voltage, anterior dominant
-generalized
‣ OIRDA (Occipital Intermittent Rhythmic Delta Activity) ✓✓-
encephalopathy eeg pattern most associated with children
-high amplitude, saw toothed, and reactive to eye opening
