Synthesis of extracted features.

Type of Feature	Feature	Comments
Band Power	Delta (1–4 Hz) Theta (4–8 Hz) Alpha (8–13 Hz) Beta (13–30 Hz) Total Absolute Power (1–30 Hz)	Epochs combined with median and std. Scalp groupings: AL, AR, PL, PR.
Functional Connectivity	Imaginary Part of Coherency (IMCOH) Phase-Locking Value (PLV) Mutual Information (MI) Partial Directed Coherence (PDC)	Epochs combined with mean, except for MI, which combines epochs with median, and PDC that combines epochs in MVAR. Five different frequency bands. Scalp groupings: AL, AR, PL, PR, spatially combined with mean and standard deviation.
Graph Measure	Efficiency Betweenness Centrality Clustering Coefficient Node Strength In and Out Degrees (directed, PDC only)	Epochs combined with mean, except for MI, which combines epochs with median, and PDC that combines epochs in MVAR. Five different frequency bands. Scalp groupings: AL, AR, PL, PR, spatially combined with mean and standard deviation.
Asymmetry Ratios	Anterior: left vs. right (AL vs. AR) Posterior: left vs. right (PL vs. PR)	Based on graph measures, which summarize connectivity matrices. Ratios only relative to mean values from Betweeness Centrality, Clustering Coefficient and Node Strengths; maximum value from In and Out degrees.
