...and for those of us who don't :-) ????
 Seriously, it worries me that there is a quasi-religious belief
 floating around in the field that LTP is the same thing as
 learning. While I have no doubt that these two phenomena (one 
 produced by the experimenter, the other prooduced by nature) do
 in fact share certain biochemical and biophysical characteristics,
 I also havee a hunch that there are certain aspects of LTP which
 are non-related to real memory formation (and I guess therefore
 could be called artifactual). That is why, I am a big fan of
 studying real learning and memory by....
 yes, studying the real phenomenon. That way the issues don't gete
 confused. We aren't left to decipher what was and what wasn't part
 of the real McCoy.

 Historically, the critisisms for my point of view tended to
 revolve around the idea that with the "study learning to understand
 learning" approach, it would be impossible to get molecular...thee
 system was too complicated. However, history (i.e. 30 years of
 research in this area) has shown that this critism doesn't hold

 Flame on (grin)
