Professor Helen Fisher conducted an experiment: what it is like for the brain when being in love. To find out how, Professor uses fMRI technology to essentially look inside the brains of 40 different men and women who have said that they were madly in love. Before she was able to apprehend the results of her scanning, she had to make an in-depth study of the brain pictures. The fMRI machine that was used showed only blood-flow activity in precise brain areas rather than the chemicals involved but the scientists knew which kinds of nerves connect which kinds of brain regions. Many brain parts became active in their love-struck subjects when they focused on their beloved. However, two regions appear to be central to the experience of being in love. Their most significant finding in the caudate nucleus, a large, C-shaped section that sits deep near the center of the brain, is very primitive. The caudate nucleus is part of what is called the reptilian brain because it developed long before mammals increased, some 65 million years ago. Their brain scans displayed that parts of the body and the tail of the caudate became mainly dynamic as a lover looked at the photo of a love. The scientists found that lovers have heightened movement in the ventral tegmental area (VTA) which another dominant part of the reward circuitry of the brain. This was what Fisher was looking for and hoped for. Before beginning, she had hypothesized that romantic love is linked with high levels of dopamine and/ or norepinephrine, which are two key neurotransmitters in the brain. Love has been said to be a drug and people get hooked onto that drug and are afraid of not having it because love releases the same neurotransmitters that are experienced when using drugs. Love and addiction are evolutionarily, socially, and chemically consistent. Fisher asked the question “What is to love?” in her Ted Talk and there are many ways to describe it. Romantic love, for one,
