What It Is
Bonn EEG set O, healthy subjects with eyes closed. 173.61 Hz single-channel surface EEG; prominent posterior alpha rhythm (~10 Hz).
Interpretation
Standard analysis sees: red spectrum (low-frequency / 1-over-f power); time-irreversible (slow rise, sharp collapse). The atlas detects no named structure beyond this. It sits beside EEG Seizure in the atlas (standard-bank rank 21) — a neighbor conventional features miss.

What the atlas adds
Nothing beyond the standard reading — this source’s structure is already captured by standard features; the atlas adds no named residual.
