Sacchet et al find that synchronization between the prefrontal and somatosensory cortex may underlie the disengagement of attention. When a cue signaled that a forthcoming tactile stimulus should be ignored, there was first an increase in alpha (7-14 Hz) synchrony between representations of the unattended stimulus, followed by an increase in beta (15-29 Hz) synchrony. This study shows how frequency specific interactions between frontal cortex and sensory cortex may underlie the focusing of attention.
