Subject specific topographical maps. Topographical distribution of electrode contribution to the reconstruction of imagined and executed arm movements for subjects 2, 7, and 8 [i.e., subjects for whom reconstruction accuracy was highest (see Figure 6)]. Color coding—contribution of significant channels [p < 0.05, Student two-tailed t-test corrected for FDR (false discovery rate)] based on accuracy rates of single channel setups in 6 × 5 inner folds indicating cortical areas providing a high contribution for trajectory decoding. (A,C) Present topographical maps for imagined and executed arm movements using band-pass filtered potentials for the PTS model, respectively. (B,D) Present topographical maps for imagined and executed arm movements using PSD values for the BTS model, respectively.
