In this video David Eagleman describes the relative perception of the passage of time varies - BUT - the markers of the passage of time (speech, physics) continues at a “normal” rate. This strongly suggests that the parts of the brain that parse the real world are locked to the world to support the interpretation of the learned world rules.
The fact that the perception of the passing of time varies strongly suggests that the “internal clock rate” can speed up.
Conclusion: there are at least two separate time scales at work here.
There is ample supporting research to support the theory that various maps in the brain resonate together as the “global workspace” is formed. I don’t have anything to offer in how the two-time scales work together.
Summation: The cycles drive synchronization on both local and global levels AND gate local discrete processing steps. This timing is not necessarily the same in all parts of the brain.
