There is a book, I think with the word ‘nature’ in the title about how there are four types of personalities. Those based on dopamine, serotonin, acetylcholine and something else (maybe norepinephrine). Does anyone know the name of this book?
The Edge Effect
Eric Braverman, MD???
I’ve surfed it but can’t speak authoritatively, does deal with dopamine, seretonin, acetylcholine, and GABA
