I still think that the dopamine system is involved in psychosis.
I’m hoping to look into it more, but my initial thinking was that the dopamine system would be involved downstream of the cortex-to-cortex connection root cause. For example, if two parts of the cortex aren’t communicating, then one can “surprise” the other (as in my OP discussion of subvocalization), and that surprise tends to (indirectly) cause dopamine release, cf. evidence cited here. (BTW I disagree with that paper’s interpretations and title, but their experimental results in themselves seem probably fine AFAIK.)
I’ll come back and write another comment when I get around to reading any of the literature on dopamine + psychosis.
One part of the neocortex might get dopamine for detecting danger, and it can rewire itself to maximise its dopamine reward by hallucinating evil spirits.
Insofar as that’s true†, it would be true for everyone, right? Do you have a guess for what’s different in people with psychosis?
