Romantic love: an fMRI study of a neural mechanism for mate choice.

Fisher, Helen, Aron, Arthur, Brown, Lucy L.·2005·Journal of Comparative Neurology

Abstract

Scientists have described myriad traits in mammalian and avian species that evolved to attract mates. But the brain mechanisms by which conspecifics become attracted to these traits is largely unknown. Yet mammals and birds express mate preferences and make mate choices, and data suggest that this "attraction system" is associated with the dopaminergic reward system. It has been proposed that intense romantic love, a cross-cultural universal, is a developed form of this attraction system. To determine the neural mechanisms associated with romantic love we used functional magnetic resonance imaging (fMRI) and studied 17 people who were intensely "in love" (Aron et al. [2005] J Neurophysiol 94:327-337). Activation specific to the beloved occurred in the right ventral tegmental area and right caudate nucleus, dopamine-rich areas associated with mammalian reward and motivation. These and other results suggest that dopaminergic reward pathways contribute to the "general arousal" component of romantic love; romantic love is primarily a motivation system, rather than an emotion; this drive is distinct from the sex drive; romantic love changes across time; and romantic love shares biobehavioral similarities with mammalian attraction. We propose that this attraction mechanism evolved to enable individuals to focus their mating energy on specific others, thereby conserving energy and facilitating mate choice-a primary aspect of reproduction. Last, the corticostriate system, with its potential for combining diverse cortical information with reward signals, is an excellent anatomical substrate for the complex factors contributing to romantic love and mate choice.

  • The brain-level attachment system is maintained in large part by the neuropeptides oxytocin and vasopressin.

    “Our particular focus will be on the brain-level attachment system [30], maintained (in large part) by the neuropeptides oxytocin and vasopressin [31, 32].”
  • When individuals view images of their romantic partner or have romantic thoughts about their partner, the NAc and VTA are recruited.

    “When individuals view images of their romantic partner or have romantic thoughts about their partner, the NAc and VTA are recruited [46,74].”
  • fMRI studies on bonding and love in humans consistently implicate DA-rich reward regions, similar to findings in prairie voles.

    “fMRI studies on bonding and love in humans provide further insights into the regions driving these social experiences and consistently implicate DA-rich reward regions, similar to findings in prairie voles (Figure 3b).”
  • Activations specific to beloved in dopamine-rich midbrain (right VTA) and caudate nucleus correlated with facial attractiveness scores.

    “They also reported that activations specific to the beloved in dopamine-rich areas associated with mammalian reward and motivation areas of the midbrain (right ventral tegmental area) and caudate nucleus (right posterodorsal body and medial parts) correlated with facial attractiveness scores.”

  • Activity in left insula-putamen-globus pallidus correlated with trait affect intensity, whereas limbic and cortical regions correlated with length of time in love.

    “Finally, activity in the left insula-putamenglobus pallidus correlated with trait affect intensity, whereas activity in limbic and cortical regions, including insula, cingulate parietal, inferior temporal and middle temporal cortex was correlated with the length of time in love.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
