Attention paradigm with ultra-long trials of 2 min and matched vision control. Ultra-long trials increased connectivity two-fold compared to 20 s trials. Attention, compared to matched visual stimulation, de-correlated visual cortex. Visual de-correlation mediated by high frequencies, other connections by all bands. Results suggest reorganization of connections by attention is frequency specific.
