Figure 23From: From wavelets to adaptive approximations: time-frequency parametrization of EEGClassical quantification of ERD/ERS in three bands: α 10–12 Hz, (β 14–18 Hz, γ 36–40 Hz. Insert indicates positions of electrodes used for recording. C3, Cz and C4 from the 10–20 system are marked by thicker circles. Results presented for electrode marked by filled circle [22].Back to article page
