Fig. 3. Spinal cord injured participant performance for 12 sessions of BMI training.

Fig. 3

(A) Participants performance at each session is shown for PCA (blue) and Kalman (red) SCI participants. Each marker type denotes a different participant’s mean performance at that session. The lines represent the map averages (n = 3 participants, 48 trials per session). (B) Improvement in performance (first – last) is shown for each map. (C) PCA was applied on 4 performance measures for all participants calculated over 12 successive sessions. Least-square elliptic fits are drawn to emphasize map differences in PC space. The matrix reports the normalized score of each performance measure along each PC. Data are means ± SEM (bars). a.u., arbitrary units.
