Who can talk about the relationship between human consciousness and emotion and human physiology, especially the brain? What is the frontier in this respect?

Non-professionals say that it can only be roughly sorted out, and authority and accuracy are not guaranteed. If there are mistakes, I still hope that careful people or experts will point them out. If the landlord is quite interested in this issue, I suggest that you can try to understand the Lenovo summary yourself after reading the encyclopedia: First of all, you should learn from high school students that the transmission on excited nerve fibers and between neurons depends on transmitters. The so-called emotion is the result of complex and diverse excitement, so that you can establish a mutual corresponding relationship between emotion and brain physiology. But whether the physiological changes of the brain reflect people's emotions or whether people's emotions will reflect the physiological changes of the brain is not clear according to my existing cognition. This is simply another copy of the question of raw eggs or raw chickens ... what is the specific correspondence? According to the current research, the brain is divided into many regions, and the central processing of external information in different regions is different. What external information is related to emotions? It seems that emotions and brain physiology can't be summarized. That's all I can say for now. Generally speaking, it is excitement ... So excitement generally affects brain physiology through the secretion of hormone information molecules. Well, I said I didn't realize it until I knew this. Consciousness is more organized and structured than emotion. However, I don't know whether it depends on matter. But if it depends on the existence of matter, it must correspond to physiological changes. I think this research is not only a problem of brain physiology, but also one of the most fundamental problems of psychology. It is not easy to say that psychology is independent of the brain branch of physiology. In other words, consciousness may not be so closely related to brain physiology, at least emotions are not closely related to brain physiology. Although the direction of the landlord's question may be in the direction of science, I think there may be a philosophical understanding: consciousness is a source, emotion is a mutual feedback between consciousness and physiology, and the physiological part of the brain is the material basis of consciousness and emotion. I said I'm not sure, and the above is not even a qualified answer. Generally, it's just my understanding to share. . .
