In this model, impulsivity provides strong parallels with addiction—with links to a specific behavior (cocaine self-administration) and to changes in signaling of a neurotransmitter (dopamine).

Luckily, monogamous prairie voles have turned out to be a good model for studying the formation of pair bonds. University of Colorado Boulder neuroscientist Zoe Donaldson found that dopamine may play ...
