Interactions between posterior gamma and frontal alpha/beta oscillations during imagined actions.

There were highly significant power suppressions during motor imagery compared to baseline, both in the alpha band (Figure 2 A -left panel; 8–12 Hz, [0 1] s after stimulus onset: p < 0.001; [−1 0] s before response: p < 0.001) and in the beta band (Figure 3 A -left panel; 16–24 Hz, [0 1] s after stimulus onset: p < 0.001; [−1 0] s before response: p < 0.001).
