Well that's interesting but raises a big question for me. Why does the brain need to couple different time scales together? Why should my breathing rate be a multiple of my typing rate. What does synchronizing processes at different time scales accomplish?

Generally speaking, information integration is entropy reduction, which is essential for life. As for what it accomplishes, think of how walking is a large rhythm involving the synchronization of many smaller rhythmic units. Or how perception of an object involves the integration of many small textures and elements into a whole. If those textures can be viewed as rhythms (FFT everything), it's another practical example of what synchronizing processes accomplishes. Singer has evidence that seeing objects as a whole uses 40hz inhibitory interneurons to synchronize the firing of features associated with a different object. So, another object would have a different 40hz phase. In that way, the synronizing creates wholes from different parts.

  Next question. If the background illumination of a room were blinking at 40Hz (Eg florescent light bulbs on 40Hz AC power), would that interfere with my visual perception? If not why not?

    It probably would, because i believe objects blinking at 40hz facilitate certain motor responses. "In addition, it has been shown in humans that stimuli which flicker at gamma frequencies are processed faster by our brains than when they flicker at different frequencies" [1] I'm super curious whether 40hz line AC might not be healthier for aging populations. Or 80hz.
