Still wondering...

I'm still curious as to whether anyone has any information or speculation 
as to the determining factors of habituation as opposed to sensitization.

As far as I can see, the two processes oppose one another.  My queries are:

	1) what causes the difference in response on a neurochemical/
	   neuroanatomical level?  is it, for example, sensitivity in 
	   the affected region; or type of neurochemical (excit or inhib)
	   at that location?

	2) although both responses have an evolutionary advantage, how
	   does the nervous system determine which is appropriate (and
	   does this ever get screwed up?)  in other words, is the type
	   of response peculiar to the stimulus?

Any ideas would be appreciated.
