Lee, Whittington, and Kopell review recent studies of the role of beta-band oscillations in top-down control of attention and model it. In their model, top-down beta rhythms activate layer-specific ascending projections that mediate biased competition. Interneurons resonate with the beta oscillations and help modulate superficial layer activity according to attentional demands.
