Figure 6From: Pure phase-locking of beta/gamma oscillation contributes to the N30 frontal component of somatosensory evoked potentialsStatistical analysis of the beta phase distribution. Evolution of the Z score (mean and SD) of the Kuiper's statistic κ. Z score is significant (p < 0.05) below a value of 0.68. Note that the highest significant values are reached around a post-stimulus time of 30 ms.Back to article page
