Adaptive dopamine regulation involves maintaining flexibility in the pleasure-pain balance and the ability to easily reassert homeostasis.

“So, in general, what we want is some kind of flexibility in that balance, and the ability to easily reassert homeostasis. We don't want to break our balance, which is possible if we overindulge for enough period of time and end up with a balance tipped to the side of pain, this dopamine deficit state we've been talking about. We want a flexible, resilient balance, right, which can be sensitive to things going on in the environment, which can experience pleasure and approach, which can experience pain and recoil, right? This is all adaptive and healthy and necessary and good.”
