Burst statistics during a motor task. a) Time courses showing the probability of bursts throughout a button press. The upper panel shows the case for the left primary motor cortex during a left hand (left) and right hand (right) movement. The lower panel shows the case for the right primary motor cortex during a right hand (left) and left hand (right) movement. b) Burst amplitude in the beta band during the post-movement beta rebound. Left-hand plots show contralateral and ipsilateral cortices during a left-hand button press. Right-hand plots show ipsilateral and contralateral cortices during a right-hand button press. * indicates statistical significance (p < 0.05*; Wilcoxon Rank Sum test) following FDR correction for multiple comparisons.
