Emotions in general are hard to define, let alone pin to a particular chemical. If I were wearing my contrarian cap I would question the extrapolation from "happiness correlates" in humans to other animals.

Sadly, that's about all the time for in depth effort posting I have today. Maybe if I had more time I'd be happy...

The mice died without dopamine by starving themselves to death...

Also, anti depressants have a strong history of effectiveness and their mechanism is dopamine re-absorption.

Regardless, I appreciate the conversation and happy holidays.
