Research from a professor at Syracuse University, Stephanie Ortigue, said that falling in love affects the intellectual area of the brain and has the same euphoric sensation as when people consume cocaine.

A study called "The Neuroimaging of Love" found that the euphoria of falling in love is the same as the effects of several euphoric-inducing chemicals, such as vasopressor, adrenaline, and oxytocin, and dopamine released in 12 brain areas that work simultaneously.

MedicalNewsToday.com had asked Professor Ortigue about “Is love linked to the brain or the heart?”

Professor Ortigue answered

"That’s a tricky question always. I would say the brain, but the heart is also related because the complex concept of love is formed by both bottom-up and top-down processes from the brain to the heart and vice versa. For instance, activation in some parts of the brain can generate stimulations to the heart, butterflies in the stomach. Some symptoms we sometimes feel as a manifestation of the heart may sometimes be coming from the brain."

The scientists also found that when a couple had just fallen in love, especially "love at first sight," their blood levels of NGF (neural growth factor) increased. NGF is a molecule that is key in human social chemistry.

With all her findings, Ortigue believes and confirms that love does have a scientific basis.
