Scalp map, PSD, dipole locations and ERSPs for cluster 3, located in the midline PMC & SMA.
(A) Cluster average scalp projection; (B) Gait cycle PSD for G, 30% GF, 60% GF and 100% GF; (C) Dipole locations of cluster ICs (blue spheres) and cluster centroids (red sphere) visualized in the MNI brain volume in coronal and sagittal views; (D) average cluster ERSP (3–45 Hz) plots showing significant changes in spectral power relative to the full gait cycle baseline (p<.05) for G, 30% GF, 60% GF and 100% GF. Non-significant differences relative to the full gait cycle baseline (p<.05) are masked in green (0 dB). The gait cycle starts and ends with R HS (i.e., 0 and 100%), the vertical line at 50% of the gait cycle marks L HS.

(A) Cluster average scalp projection; (B) Gait cycle PSD for G, 30% GF, 60% GF and 100% GF; (C) Dipole locations of cluster ICs (blue spheres) and cluster centroids (red sphere) visualized in the MNI brain volume in coronal and sagittal views; (D) average cluster ERSP (3–45 Hz) plots showing significant changes in spectral power relative to the full gait cycle baseline (p<.05) for G, 30% GF, 60% GF and 100% GF. Non-significant differences relative to the full gait cycle baseline (p<.05) are masked in green (0 dB). The gait cycle starts and ends with R HS (i.e., 0 and 100%), the vertical line at 50% of the gait cycle marks L HS.
