To experience rejection is to feel deep emotional pain. Scientists, however, have gathered evidence to suggest that emotional pain and physical pain are not so vastly different — neurologically speaking. An fMRI study, published by the American Association for the Advancement of Science, found that patterns of brain activation during times of social exclusion are similar to those that occur during moments of physical pain. Additional research out of the University of Michigan has indicated that personality traits like "resilience" differ according to variations in the brain's natural painkilling response. Other studies have attempted to more finely parse the differences between the neural representations of rejection and pain, but their neurochemical overlap continues to provide insight into the brain's overarching regulatory responses to stressors of all kinds.   

 Many psychologists interpret the pain of rejection as a link to our evolutionary origins as members of cooperative societies whose survival depended upon strong social bonds (for more information about humans' social evolution, read this article from Science Magazine, or check out this overview of the history of homo sapiens from the Australian Museum). However, none of this scientific understanding lessens the hurt we incur when we are the rejected party. Some people find themselves more sensitive to rejection than others, but studies have found that self-regulation can help individuals manage their hostile and damaging responses to the heightened fear of rejection.
