Dissociable Learning Processes Underlie Human Pain Conditioning
Zhang S., Mano H., Ganesh G., Robbins T., Seymour B.
© 2016 The Authors. The classical "fear" response elicited by the brain in the presence of threat is critical for survival. Using pain as the threat, Zhang et al. show that autonomic and motor defensive reactions are associated with multiple learning systems. This means the overall phenotype of pain-based fear response is the sum of partially independent processes.
