Figure 2. Diagram illustrating one mechanism by which long-range gamma synchrony might facilitate communication between brain regions in a dynamic fashion.

Figure 2

In this example, during a visual task, gamma oscillations occur in visual regions and PFC, and are synchronized across these regions. If requirements of the task shift, such that visual information is no longer required, but auditory information is, then changes in the patterns of oscillations can facilitate a rapid shift that favors the flow of auditory information into PFC.
