Thanks, Edwin.  That was actually the point of my objection to Ken's
statement.  I was protesting the idea that neurons are generally
larger (volumetrically) than other types of cells.  Your points about
DNA content not being the same in all cells is also well taken, but
that wasn't what I was on about at the time...

Well, actually what you're probably remembering is my quote of Larry
Palmer, "it's been estimated that there are 10^12 neurons in the human
nervous system, 10^13 of which are in the cerebellum".  Or perhaps
you're remembering Ken's posting of the 10^11 estimate that made me
post the joke in the first place.

Come on, Stan, you should know me better than that by now...
