Womeldorf et al observed bursts of firing in the anterior cingulate and prefrontal cortex during shifts of attention.  These bursts (but not non-burst firing) synchronized over long distances (between the AC and PFC) to local field field potentials at beta and gamma frequencies.  These bursts were proceeded by bursts of inhibitory neurons.  The authors propose burst firing mechanisms help form functional networks to coordinate shifts of attention.
