What It Is
PhysioNet resting-state EEG, 109 subjects, contiguous blocks at 160 Hz across 64 channels (first channel sampled here). Broadband noise with intermittent alpha bursts.
Interpretation
Standard analysis sees: red spectrum (low-frequency / 1-over-f power). The atlas finds no named structure, but the source is distinctively extreme on AutoRegressive:ar_coef_4 (-7.1z) — beyond what the standard bank predicts for it.
