wavelet transforms (Delorme and Makeig, 2004; Ford et al., 2008; Roach and Mathalon, 2008; Tallon-Baudry et al., 1996), but to circumvent characteristic time-smearing (low time-frequency resolution) associated with wavelets, we used reduced interference distribution (RID) transforms belonging to Cohen’s class to compute energy (real-valued RID-binomial) and PLF (complex-valued RID-Rihaczek). The time-frequency transforms used here provide uniform resolution whereas wavelets do not (Aviyente et al., 2011; Aviyente and Mutlu, 2011; Bernat et al., 2005).
