Modulation of Long-Range Neural Synchrony Associated with Changes in Visual Attention

A large number of studies have so far tried to uncover the rules governing the attention-driven modulation of bottom-up processes [1] and succeeded in identifying areas for the attentional control of visual processing among which frontal, temporal and parietal areas play a prominent role. Still, little is known about the mechanism by which these areas interact. We used magnetoencephalography to study transient long-range neural communication, by means of phase synchronization among these areas, in a challenging task which induces deficits of temporal visual attention. Two target letters embedded in a stream of 1…
