Heartbreak isn't "just" emotional — brain imaging research shows it activates some of the same regions involved in physical pain and addiction.
Helen Fisher and colleagues used fMRI to study brain activity in recently rejected people, publishing peer-reviewed findings in the Journal of Neurophysiology. Looking at photos of a former partner activated the nucleus accumbens and orbitofrontal/prefrontal cortex — regions also associated with cocaine and cigarette addiction — along with the insular cortex and anterior cingulate, regions tied to physical pain and distress. There's a genuinely hopeful finding too: the more time that had passed since the breakup, the less activity there was in the brain region associated with attachment.
This guide covers what the research actually shows and what it means for how healing happens.
