“…These studies found that the patterns of cortical activity of experts and nonexperts are different (Abernethy & Russell, 1987;Bhattacharyaa & Petsche, 2002;Bird, 1987;Collins, Powell, & Davies, 1990;Crews & Landers, 1993;Fink, Graif, & Neubauer, 2009;Hatfield, Landers, & Ray, 1984;Haufler, Spalding, Maria, & Hatfield, 2000;Karkare, Saha, & Bhattacharya, 2009;Panga, Nadalb, Müllerc, Rosenbergd, & Kleine, 2012;Petsche, Lindner, Rappelsberger, & Gruber, 1988;Petsche, Richter, Stein, Etlinger, & Filz, 1993;Radlo, Steinberg, Singer, Barba, & Melinkov, 2002;Salazar et al, 1990;Shourie, Firoozabadi, & Badie, 2011, 2013Wagner, 1975aWagner, , 1975b. Most of the previous research has focused on the power spectrum density of the traditional EEG rhythms, which may not be reliable due to the nonstationary nature of the EEG signals (Collins et al, 1990;Crews & Landers, 1993;Fink et al, 2009;Hatfield et al, 1984;Haufler et al, 2000;Petsche et al, 1988;Petsche et al, 1993;Radlo et al, 2002;Salazar et al,1990;Shourie et al, 2013;Wagner, 1975aWagner, , 1975b. Hence, time-frequency features are highly reliable for EEG signal analysis.…”
