The biomarkers
What the interpretable features look like
Median-over-epoch, region-level values for the development cohort (ds007526), healthy controls vs. Parkinson's. De-identified aggregates — no raw signals, no participant ids. Boxes show the interquartile range; the line is the median; whiskers span the observed range.
Peak alpha frequency (occipital)
Theta / alpha ratio (central)
Relative alpha power (occipital)
Relative theta power (frontal)
Relative beta power (occipital)
Spectral entropy (occipital)
Hjorth complexity (occipital)
Exploratory only — no statistical test is implied, and overlapping distributions are expected. Group differences may reflect demographics or acquisition rather than disease. The interactive per-dataset explorer lives in the Streamlit dashboard.
