Emotional pain shares the same neurology as physical pain


The Neural Bases of Social Pain: Evidence for Shared Representations With Physical Pain
NAOMI I. EISENBERGER, PHD
Experiences of social rejection or loss have been described as some of the most ‘‘painful’’ experiences that we, as humans, face and perhaps for good reason. Because of our prolonged period of immaturity, the social attachment system may have co-opted the pain system, borrowing the pain signal to prevent the detrimental consequences of social separation. This review summarizes a program of research that has explored the idea that experiences of physical pain and social pain rely on shared neural substrates. First, evidence showing that social pain activates pain-related neural regions is reviewed. Then, studies exploring some of the expected consequences of such a physical painYsocial pain overlap are summarized. These studies demonstrate that a) individuals who are more sensitive to one kind of pain are also more sensitive to the other and b) factors that increase or decrease one kind of pain alter the other in a similar manner. Finally, what these shared neural substrates mean for our understanding of socially painful experience is discussed. Key words: social pain, physical pain, dorsal anterior cingulate cortex, anterior insula, brain, fMRI.  Here is the link.
