Emotions are allostatic processes that transform the relationship between the environment and the desired bodily states into behaviour supporting homeostasis and well-being. Central emotion circuits are thus tightly coupled with the visceral signaling pathways and the autonomic nervous system (ANS). Although ANS activity patterns are not always emotion-specific, self-reported bodily sensations and pattern recognition analysis of functional magnetic resonance imaging data suggest discrete bodily and neural basis of emotions. The advent of total-body positron emission tomography (PET) systems allows simultaneous measurement of the central and peripheral axis of the emotional response. This provides a unique opportunity for quantifying the systems-level biology of the human emotion circuits.
