From: Hebbian plasticity induced by temporally coincident BCI enhances post-stroke motor recovery
Spectral power pre-treatment minus power post-treatment in each group. Spectral power reduction was greatest from pre- to post-treatment over contralateral (ipsilesional) primary motor cortex in the BCI-FES group. Note that the positive T-values indicate a greater desynchronization post- than pre-treatment. Black contour = cluster of adjacent time–frequency points at which the post- vs- pre-treatment power differed according to paired T-tests at threshold p = 0.05. (A) BCI-FES group: at each electrode. (B) BCI-FES group: largest cluster observed at electrode C2, over right primary motor cortex. (C) Random-FES group: at each electrode. (D) Random-FES group: at electrode C2, over right primary motor cortex. Cluster-based permutation testing showed a significant difference between spectral power pre- and post-treatment in the BCI-FES group (p = 0.036).
