EEG Atlas

Build a visual reference for normal patterns, artifacts, and abnormalities.

External learning resource

Atlas of Adult Electroencephalography

Explore annotated EEG examples on the atlas website. Open it in a separate tab to keep the complete recording and electrode labels visible.

Open the EEG atlas

The atlas is maintained by its own authors. Access and registration are managed on that site.

Make each example a reading exercise

Orient: identify the montage, electrode labels, time scale, and sensitivity.
Describe: note frequency, amplitude, distribution, and how the pattern changes.
Compare: read the annotation, then return to the tracing and find the supporting features.

Practice the sequence in EEG Fundamentals, then check your interpretation in the Question Bank.
