   Well, just resizing the brain might not work too well.  There was an   
   article in Scientific American (July, 2011) about that.  The author   
   found that increasing the size of the brain might not help, because   
   of that old communication speed problem.  It seems that we are   
   approaching the point of diminishing returns.
