Functional dissociation for alpha-band synchronization across local and long-range cortical scales during STM retention. a Average alpha-band phase locking between sensors over posterior cortex and all other analyzed sensors during STM retention (left) and the time course of this long-range synchronization throughout STM retention and the baseline period averaged across posterior sensors (right). b Average alpha-band amplitude at posterior sensors during STM retention (left) and the time course of this local desynchronization throughout STM retention and the baseline period averaged across posterior sensors (right). Amplitude changes and phase synchronization are expressed in units of standard deviation from the baseline. Gray horizontal lines indicates temporal discontinuity (the period of S1 presentation between the baseline and retention intervals)
