Speaking with Buzsáki, I found myself wondering what my brain was actually sensing when I seem to feel time flowing, second by second, minute by minute. "It has to be measuring something else, such as a change or speed or acceleration, for which we do have sensors," Buzsáki told me. If that's the case, then "time" isn't an absolute thing that our brains can "track" or "measure"; it's more like an organizational system for making sense of change in the world around us and coördinating our lives.
"Of course time is change," Edvard Moser agreed. Another way to describe his lab's analyses of the L.E.C. would be to say that it uncovered changing sequences of activity during episodes of experience. "We call it 'episodic time' to emphasize that this is not 'clock time,' " he said.
