I really wish I could get into that paper. I’d like to know whether was dopamine precursor given to the rats before the retest to enable eating? If so the learning may have been buffered and acquired through sleep or there is a different method for learning in sleep. I’ll see if I can get to it in the next few days.
I’d agree that some learning did occur without dopamine, the knowledge of where to go was learnt. The brain is to complex to mediate all learning with direct feedback. What we are interested in is learning what should be done. That is the behaviour was learnt but that the behaviour should be performed wasn’t immediately learnt. Or in other words it didn’t know it should be motivated.

There is lots of work on dopamine and learning. I’m currently watching another interesting video on the subject.
Do you know of any related to opioids? All I can find some stuff on fear response learning.
My school let me at the full text of the paper; here ’tis.
Thanks. I’ll read it later.
