Since the brain is unlike any other structure in the known universe, it seems reasonable to expect that our understanding of its functioning - if it can ever be achieved - will require approaches that are drastically different from the way we understand other physical systems.

Stop thinking of sleep and naps as “downtime” or as a “waste of time.” Think of them as opportunities for memory consolidation and enhancing the brain circuits that help skill learning. Nor should you feel guilty about sleep. It's just as crucial a part of successful brain work as the actual task itself.

I believe there's only one answer to that question, and perhaps it will disturb you: there is no model of the brain, nor will there ever be. That's because the brain, as the constructor of all models, transcends all models. The brain's uniqueness stems from the fact that nowhere in the known universe is there anything even remotely resembling it.
