i knew it was glutamate all along, Frank, but glutamate was referenced in
one of the refs i read in response to the work John's doing... so, since
folks knew i was 'over-there', i didn't bother.

my earlier ref to kainic acid was a reference back to a series of
presentations i gave at Smith College back in the 80s.

excitotoxicity is excitotoxicity... the nervous system 'moves away from'
such... glutamate is in-there, but it's normally well-controlled, except
when lesions disrupt the intact mechanism, as in strokes or epilepsy.

all of this is in AoK, Frank, if you'd 'just' =Think=, instead of 'moving
away from'...

...guess AoK's just a bit to 'exciting' for you to deal with :-)
