       | EEG is not a great method overall as it measures electrical
       | activity and data is hard to understand and reason about
       | theoretically. I think it stands to reason that studying
       | electrical activity in certain arbitrary frequency bands doesn't
       | tell us a lot about the brain other than its coordination and
       | power-states (A good computer analogy might be ACPI power
       | states).

         | That might be true for now given our limited understanding. But
         | would you really bet against this in the long run? Moreover,
         | the article outlines considerable evidence that such
         | coordination and frequencies have been empirically associated
         | with conscious perception.

         | intense and surreal and include a panoramic life review with
         | memory recalls, transcendental and out-of-body experiences with
         | dreaming, hallucinations and a meditative state_
         | 
         | Finally, given the large body of anecdata and subjective
         | evidence, don't you think it's a bit dismissive to suggest that
         | the brain's capacitors are simply sputtering out?
