What happens to the brain when you experience love?

Have you ever wondered what really goes on in your brain when you experience different stages of love?

Words often fail to convey the intense power of love – in all its forms. Whether it’s the intoxicating feeling of falling in love, the joy of holding your child for the first time, or the wonder of the world’s beauty, love permeates every aspect of our lives. But have you ever wondered what’s really going on in your brain when you experience different levels of love?

A groundbreaking study published in August 2024 in the journal Cerebral Cortex unraveled this mystery. Through rigorous testing, scientists took us deep inside the mind, revealing how the brain experiences six distinct types of love and how each type activates different neural pathways. From love for people, to love for animals, to love for Mother Nature, the study revealed which type of love has the most profound impact — and why.

Romantic love

Romantic love is often considered one of the most intense and dominant forms of love. It’s a type of love that can be physically and mentally overwhelming, and its power was clearly reflected in the study’s fMRI results. When people thought about their partner, a number of key regions of the brain lit up — particularly those involved in emotion, decision-making, and memory.

The brain regions that are highly active during romantic love include areas associated with pleasure and reward, such as the striatum and orbitofrontal cortex. These are regions that activate in situations where we feel valuable, like when we enjoy a favourite food or win a game. This may explain why romantic love feels so euphoric—because the brain actually perceives it as extremely valuable. Furthermore, activation in the brain stem—the region that regulates basic bodily functions—suggests that romantic love can have a profound, almost primal effect on us.

While many people may view romantic love as simply a “chemical reaction,” this research demonstrates the immense power that this response has. It is not a fleeting love, but a powerful force that can shape our thoughts and actions at a fundamental level.

Parental love

Parental love is another powerful emotion, often described as unconditional and self-sacrificing. This is the kind of love that drives parents to protect and nurture their children – even at the cost of their own lives. This love is vital to the survival and well-being of their children, and it is clearly reflected in the way their brains respond.

The brain regions activated by parental love overlap significantly with those involved in romantic love, suggesting a strong emotional bond between parent and child. However, parental love has a unique feature: when parents think about their child, the brain’s reward system becomes even more active, especially in the striatum and thalamus. This suggests that the happiness and satisfaction parents feel when caring for their child is deeply rooted in our biology – and that its rewarding properties may be superior to any other type of love.

This increased reward response may explain why parental love is so deeply fulfilling, and why parents often describe their relationship with their children as unlike any other. It is a love that is both emotionally intense and deeply satisfying – factors that motivate us to ensure a happy future for the next generation.

Love for friends

Friendship, also known as Platonic love, is an integral part of our social lives. Friends are not only a source of support, but also a source of inspiration, kinship, and a sense of belonging that enriches our lives. Although love for friends may not be as intense as love for a spouse or family, it is still vital to our happiness and mental health.

Scientists have found that friendly love activates many of the same brain regions as romantic love and parental love, but to a lesser extent. This suggests that while friendships may not be as emotionally intense as more intimate relationships, they are still deeply important for maintaining social well-being. Brain regions associated with social bonding — such as the temporoparietal junction and the cingulate cortex — remain activated, demonstrating the importance of friendships in maintaining social bonds.

Interestingly, the brain also shows activity in regions associated with empathy and social cognition—such as the posterior superior temporal sulcus and temporal regions—which may explain why good friendships are often accompanied by deep levels of empathy and understanding. While Platonic love may not be as intense as romantic love, it is still a powerful and enduring force that enriches our lives in countless wonderful ways.

Love for strangers

Stranger love may seem strange, but it is actually the natural feeling of goodwill and empathy we have for people we do not know. This kind of love is the invisible thread that holds society together, helping us treat each other with kindness and cooperation.

The brain’s response to love for strangers is milder than that of close relationships, but there are still noticeable signs. Areas involved in social processing and recognizing others are active, but not as strongly. This makes sense because our feelings for strangers tend to be less profound. However, the cingulate cortex—a region involved in empathy—is still activated, suggesting that we do care about them. Still, this type of love doesn’t produce the same deep emotions as falling in love with someone we know.

Though not as intense, love for strangers plays a key role in maintaining peace and harmony with those around us. It is the driving force behind the altruistic acts and kindness we show others, even when we have no personal connection.

Love for pets

For many people, pets are more than just animals; they are beloved family members. The love we have for them is often profound – because they provide us with a unique sense of comfort, companionship, and joy. This bond is especially meaningful for those who have spent their lives with a beloved pet.

Research shows that love for pets activates brain regions associated with social bonding and pleasure, similar to love for humans, but to a lesser extent. In particular, pet owners show more brain activity when thinking about animals than non-pet owners. This suggests that the relationship between pets and owners is unique and difficult to fully understand unless you have experienced it yourself.

Interestingly, brain regions such as the anterior cingulate cortex and posterior cingulate cortex – which are involved in self-reflection and social information processing – are more active in pet owners. This may explain why they often feel a particularly deep connection to their pets, viewing them as indispensable members of their social circle, just as important as their human friends.

Love of nature

Love of nature is a special kind of love that connects us deeply to the beauty of the world around us. It’s the feeling of peace when you walk through a forest, the silence that fills you when you stand by the ocean, or the awe at the majesty of a mountain. This kind of love not only nourishes the soul but also inspires us to protect and preserve nature.

When participants thought about nature, brain regions involved in visual processing and spatial awareness—such as the fusiform gyrus and parahippocampal gyrus—were activated. This makes love of nature unique, as it does not stimulate regions involved in social bonding like love between people does. Instead, it stems from an appreciation for the beauty and vastness of the natural world, which motivates us to take action to protect the planet.
