I want to know the answer to the following question:
What system was examined to develop the neurobiological explanation of human emotion?
All the background I'm provided with is that "If distinguished from reactive responses of reptiles, emotions would then be mammalian elaborations of general vertebrate arousal patterns, in which neurochemicals (for example, dopamine, noradrenaline, and serotonin) step-up or step-down the brain's activity level, as visible in body movements, gestures and postures.". Is that enough to answer the question?
Answer: no
