Don't jump so many levels from chemicals to the central nervous system. The jump of complexity is so immense that you would never be able to integrate the two sufficiently to provide a basis for a living human being.
Chemicals in the brain are molecules. Emotions first happen on the level of tissues. What role do molecules play in tissues?
First you integrate molecules with crystal lattices into organelles, such as chromosomes, which hold you DNA, then you integrate organelles with cellular cytoplasm into cells, such as blood cells, then you integrate cells with cellular matrix into tissues, such as blood tissue. The electromagnetic wave that is the context of each of such tissues while it's living generates emotions.
Emotion is an experience that happens through your heart (this is not a metaphor). Thoughts go through the tissues of your nervous system. Thoughts start in your brain. They are the integrated interactions of neurons, aka their firings, within electromagnetic waves. Thoughts also initiate your emotions, that is, they start emotions but do not end or complete them.
Does the mainstream "science" care about tissues more than about molecules or cells? Not really. That's a problem. How come the only ones who do care are called "pseudoscientists"? The answer lies between molecules and organs, as I've shown.
What about the excitement you feel in preparation for sex? That's an emotion. And the pleasure you get from sex is also an emotion. Why dichotomize positive emotions? It doesn't matter whether you are feeling emotions before or during the mating experience, you are still feeling emotions, not mere thoughts, unless you are having an intercourse without much feeling.![]()
