In the realm of romantic connections, a study by CU Boulder neuroscientists involving prairie voles reveals a biological signature of desire, shedding light on why we feel a stronger pull towards certain individuals.
The research shows that the neurotransmitter dopamine plays a crucial role in nurturing long-term bonds.
Let's see what they've discovered.
How love changes us
Prairie voles, much like humans, form monogamous pair bonds and share a range of experiences with their partners.
By observing these rodents, researchers aim to understand the neurochemical processes underlying human intimate relationships and how the brain copes when such bonds are severed.
The study indicates that specific individuals leave a unique chemical imprint on the brain, influencing the desire to maintain these bonds over time.
How it was studied
Using advanced neuroimaging technology, the researchers measured real-time brain activity in voles as they sought their partners, revealing that dopamine levels surged when reuniting with a life partner compared to encountering a stranger.
The study suggests that understanding healthy bonds at a neurological level could inform therapies for mental illnesses affecting social connections.
