What activates the pleasure and reward centers of the brain, calms parts of the brain associated with fear and anxiety, and is available to anyone without a prescription?
Researchers Bianca Acevedo, PhD and Arthur Aron, PhD took ten women and seven men who had been married an average of 21.4 years and did fMRIs to look at their brains.
They wanted to see what was happening in their brains while participants looked at photos of their partners.
For a comparison, they also saw photos of a highly familiar acquaintance, a very close, long-time friend, and a less familiar acquaintance.
When looking at their long-term partners, the areas of the brain affected were associated with dopamine reward (like the ventral tegmental area, which is involved in intense emotions relating to love).
This activation is similar to what is seen in the euphoric early-stages of love.
But the difference in long-term relationships vs. new ones is this: brain areas associated with attachment (like the insular cortex and anterior cingulate) were also activated during the fMRIs when looking at long-term partners, as were areas related to learning, memory, and neurohormones (from the hypothalamus).
Overall, people who were happily involved in long-term relationships had increased activation of their pleasure-reward circuits and parts of the brains relating to attachment and bonding.
Not only that, but the parts of the brain associated with anxiety and fear were calmed as well.

Would you like to know more about the neurobiology of love?
I will be talking with neuropsychologist Marsha Lucas, PhD, on How to Mindfully Rewire the Brain for Love as part of the New Brain Science 2012 series.
We will discuss many topics, including:
- Why rewiring the brain can help improve sex
- What happens in the brain when we’re afraid
- How your vagus nerve can help you project peace and safety to the people around you
- One simple practice that can rewire the brain for serenity instead of fear and over-reactivity
