Cover legend: Representation of magnetoencephalography channels showing a large decrease of beta-band power during the perimovement period of an instructed-delay task in which subjects reached from a center position to a peripheral target. For each channel, the color indicates the number of subjects for which that channel showed a large decrease in beta-band power (white: 0 subjects to red: 5 subjects). For more information, see the article by Tzagarakis et al. in this issue (pages 11270).
