Topography of the relationship between verbal memory performance and alpha power decrease.

<p>Panel <b>A</b> illustrates significant cluster of MEG sensors (p_cluster<0.01) obtained after correction for multiple comparisons. Sensors belonging to the significant cluster are marked with black circles. Color bar indicates range of correlation coefficients. <b>B</b>: Relationship between change in verbal memory (VM) performance (abscissa, positive values indicate more improvement) and pre-to-post-training change in alpha power decrease (ordinate, negative values indicate more alpha power decrease, thus, improvement) by patient training group based on the ROI in 5A.
