The PATH is made ready before the JOURNEY is made.: I figured
  out a link between 'uncertainty principal" and the "all or none"
  law in the the brain. In quantum physics, an electron (for
  example) has the potential to be in a number of places, but it
  is "more likely" to be in some places rather than others. In the
  end, it does choose a path. or better still: LIGHTNING: It finds
  a path from A to B - but you can't predict exactly how it will
  get there. Now, the brain part: In the brain, before a neuron
  fires, its "likely paths" are depolarized - a SPACE is opened up
  for it to activate. THEN the neuron fires, choosing, as it were,
  a way to get where it needs to go. An analogy, from "The Wave
  Watcher's Companion" is: "This is a little like a person
  becoming excited, and thereby more likely to start shouting."
  Or, I think of it as the smart way to move heavy furniture:
  Clear out a path BEFORE you start lifting the furniture. Get the
  chairs out of the way, open all doors, make sure the path is
  wide enough. You don't NEED all that space, but you have to make
  it as easy as possible to DO IT RIGHT. This is a feature built
  in to nature. and I find this quiet awesome. = The awesomeness
  for me is that I've been skeptical of the whole, 'can't measure
  an electorn's position and direction at the same time" without
  disturbing it. See, the POTENTIAL paths, locations, etc are
  setup AHEAD of time. The fact that measuring in some way
  disturbs things, while cool, it's simply one 'particle' bouncing
  off another, affecting it. BUT the fact that there is ALREADY a
  path for it to "make that choice from' is cool. the path is made
  ready before the journey is made... == Unlock all the doors of a
  house where you think your guests mght need to go into. YOU
  DON'T KNOW ahead of time what your guests will do, so you get
  ready for whatever possibilities may arise. the guests choose
  their own paths. YET by keeping some doors locked (the paths
  they CAN'T go in) you have set up ACTION POTENTIAL. == Now I
  wonder if lightning does the same thing - sets up a 'potential
  path' (defining the area it MIGHT travel in) BEFORE the bolt
  strikes? I bet it does.... almost a 'one two' punch: first the
  scout goes out to see what's ahead, clearing a path if
  necessary, before the team travels through == Got it: It must be
  like the "Advance wave' just before a plane breaks the sound
  barrier - all the waves compressing in front of each other
  BEFORE the plane breaks through. the Action Potential iis the
  advance wave -- but there's no guarantee that the plane will
  break through... just like how the ENTIRETY of the path cleared
  befor the neuron firing will get used; Either a particular bit
  gets used, or it doesn't ("all or none"). Man, I wish I could
  draw - i can picture how it works. Love capturing a new concept
  / a new connection i hadn't thought of before. Feb 14, 2012
