Slime mold conditioning

I remember reading about slime mold habituation research from a while ago, but can't remember if there has been any research on slime conditioning (pavlovian).

An example might be that the researchers expose the slime to a neutral chemical minutes before subjecting it to the cold. After a few runs, the slime learns to react to the neutral chemical in the same way it reacts to the cold.

I was wondering if anybody could remember any examples of slime conditioning.
