Characteristics of the decoding models for 3D hand positions. (A) Spatial contributions of different electrodes, W_s(ch), for 3D hand positions. Median W_s(ch) across decoding models obtained from different experiments are shown (n = 13, 10, and 12 for A-DL, A-DF, and K-C, respectively). For each position, the electrodes with contributions significantly greater than their median (p < 0.01) are circled by thicker lines. (B) Spectral contributions of different frequency bins, W_f(freq), for 3D hand positions. For each position, the frequency bins with contributions significantly greater than their median (p < 0.01) are marked with asterisks. (C) Temporal contributions of different time lags, W_t(lag), for 3D hand positions. For each position, the time lags with contributions significantly greater than their median (p < 0.01) are marked with asterisks.
