Hi Matt. I enjoyed reading your discussion
except for one thing :-]

OK, show me a "current" in the absence of
a "conductance".

In nervous systems, "current" is embodied
in ion's motions - "conductances".

Forgive me, please, it seems that, these 'days'
I'm thrust-into work that entails eliminating
redundant usage in symbolic representations.

It's not "trivial". All the extra stuff that's heaped-
up in the symbolics 'blinds' folks to what's act-
ually going-in in-there.

Please Forgive me. I'm not 'jumping' =you=.

I'm working to Fix what needs Fixing in the books.

Cheers, Matt, ken [k. p. collins]
