I could not find an answer to my question in academic literature so I hope someone who has training in neuroscience or know of research articles that answer this question can help. I was wondering if neuronal activity associated with emotions that we feel localised in our bodies (i.e. excitement or fear in the stomach) can be detected using existing methods like MRI or something else. And if such activity could have distinct pattern or dynamics. The ultimate question is to look for such neuronal activities in animals as an evidence that they do have emotions. This could prove consciousness (whether of a similar or different degree) in animals, at the same time bypassing the problem that we do not understand the mechanism of consciousness. The point is that why have emotions like we do without something out there to feel them. Because although consciousness is tended to be interpreted as a characteristic of high intelligence associated with humans, I believe that the fact that we consiously feel these emotions hints at an evolutionary function of consciousness that is not tied with thought and intelligence and therefore seems more “primitive” so that it could be a widespread conserved mechanism in higher animals. There are many indirect hints at their emotions like responding “subjective” behaviour to emotions similar to us e.g. trembling in fear, love partners rubbing faces like in parrots for example. What I ultimately mean is that it is more probable that consciousness and associated feelings (including feeling pain) are an evolutionary mechanism older than humans that is conserved in us, because it is not associated with what makes humans distinct from out closest non-human ancestor. What makes us distinct is increased problem solving, logic and most importantly complex language that allowed technical and scientific progress to build up and evolve, I think this is what makes humans unique and not conscious feeling of fear or love and for that matter consciousness at all. This is an interesting question to answer experimentally and if animals are conscious then cattle needs much better treatment, also decreasing meat consumptions can reduce pandemics occurrence and CO2 emissions.
