Really chuffed about this one. It's impt for our efforts to understand neural and computational bases of controlling the contents of WM. It also highlights a control-related signal in the beta band that is NOT "inhibitory" in the way often assumed doi.org/10.1523/JNEU...

Prioritization in Working Memory Reduces Interference via Beta Band-Linked Stimulus Transformations
We studied the effects of prioritization in a two-step retrocuing task in which male and female humans hold two items in working memory, and the item not cued by the first cue cannot be dropped becaus...
