This is how the brain lights up when we kiss someone we love

This is the first image in the world obtained from an RMI magnetic resonance imaging that shows the bond between mother and child.

A kiss causes a chemical reaction in the brain, including a burst of the hormone ocytocine. It is often called the love hormone because it causes feelings of affection and attachment. A kiss activates the brain's reward system, and this releases dopamine, which makes us feel good. It also releases vasopressine which bonds mothers with babies, or romantic partner. It also releases serotonin which helps regulate our mood.
