fluence by previous non-invasive and ECoG studies that demonstrated the importance of low frequencies for non-invasive decoding (Jerbi et al., 2007; Schalk et al., 2007; Walden et al., 2008; Bradberry et al.. 2008, 2009a). Next, the temporal difference of the EEG data was computed (i.e., ;Ed= [t —1] where ;[

ional trajectories have been decoded from LFPs (Mehring el al.. 2003. 2004; Leuthardt et al.. 2004; Rickert et at. 2005: Scherberger et al., 2.005; Schalk et al., 2007: Pistohl et al., 2008; Sanchez et al., 2008). In the late 1990s, pioneering work on the macroscale began to relate scalp potentials acquired
