According to a new research, both brain and heart are responsible to make someone fall in love.

Lead researcher Stephanie Ortigue of Syracuse University and her team studied the previous brain research intended to understand love and noticed that as many as 12 areas of brain work together when someone falls in love.

The researchers found that when someone develops the feeling of love for the other gender, various areas of brain triggers the release of euphoria-inducing chemicals like dopamine, oxytocin (also known as love hormone), adrenaline, and vasopressin.

Some other studies suggest that blood levels of nerve growth factor (NGF) when one falls in love also increase. The NGF is a protein that helps in the survival and maintenance of brain cells. The study also noticed considerable increased level of NGF in those couples who had just fallen in love.

Ortigue said that the results indicate that there is a scientific basis for falling in love.

She stated, “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”.

The findings of the study will be published in the latest edition of the Journal of Sexual Medicine.
