EEG BOARD EXAM 2025/2026
Enhanced EEG Board Study Guide
Original Exam-Preparation Edition • Technical Sciences • Electrode Placement • EEG Interpretation • Safety
This original guide is inspired by the public preview of the referenced Stuvia listing. The listing is a 60-page 2025/2026 exam-elaboration
resource. Its public preview includes EEG physiology, the International 10–20 system, alpha rhythm, Nyquist sampling,
flammable-material storage, collodion, calibration, damping, digital resolution, filter settings, and activation procedures. The material below
expands these themes independently and does not reproduce paid or locked content. ■cite■turn0view0■
Study Strategy
• Master frequency bands and normal variants before pathology.
• For technical questions, think signal → electrode → amplifier → filter → display → artifact.
• For pattern questions, identify location, frequency, morphology, state, reactivity, and clinical context.
• For safety questions, prioritize patient safety, electrical safety, infection control, and chemical/fire safety.
• For certification preparation, verify current professional standards and laboratory policies.

, SECTION — EEG Fundamentals
EEG records voltage differences generated primarily by synchronized cortical neuronal activity detected through scalp electrodes.
The signal is influenced by cortical generators, electrode placement, reference choice, impedance, amplification, filters, sampling, and
display settings.
A waveform should never be interpreted in isolation: frequency, amplitude, morphology, distribution, state, reactivity, and artifacts all
matter.
Exam Drill
Ask: What is the signal? Where is it maximal? What is its frequency/morphology? What state is the patient in? Could artifact explain it?
What technical or safety principle is being tested?

, SECTION — International 10–20 System
The 10–20 system standardizes electrode placement using proportional measurements based on skull landmarks. Odd numbers generally
refer to the left side and even numbers to the right; midline sites use Z.
Anterior-posterior and lateral chains provide reproducible spatial sampling of scalp electrical activity.
Know the common landmarks and electrode families conceptually; exact placement questions should be answered using the applicable
laboratory/standard reference.

, SECTION — Frequency Bands
Delta is the slowest conventional band; theta is slower than alpha; alpha is classically prominent posteriorly during relaxed wakefulness
with eyes closed; beta is faster and commonly associated with wakefulness and medication effects.
Frequency alone does not establish pathology. State, age, medication, drowsiness, sleep stage, and artifact alter the appearance.
Always pair frequency with morphology and clinical context.
