Humans think love is a sense that is difficult to understand. However, this contrasts with the opinion of a scientist who says that love is only a series of chemical events. According to Larry Young, professor of neuroscience at Emory University in Atlanta, Georgia, love can be explained by a series of neurochemical events in certain parts of the brain. If this opinion is true, then people don't need to rely on chocolate or oysters to arouse feelings of love. In fact, people can create aphrodisiacs that make someone fall in love at first sight or antidote for unrequited love because they love someone who shouldn't. 

Scientists have previously observed that a chemical called oxytocin is involved in the development of bonds between mother and child in animals. Prof. Young believes, things that happen to animals also occur in humans. "It's just that when we experience these emotions, we can't imagine that it's just a series of chemical events," he said. Researchers have found that oxytocin is involved in male and female bonds, forming a strong bond with each other for a very long time. And there are studies in humans that show increased oxytocin can create the ability to read other people's emotions. 

Prof. Young believes, there are still other chemicals involved. "I'm sure this is just the beginning. There are hundreds of molecular signals in the brain and all act in different brain regions, one day we will have a better understanding of how all these chemicals interact and act in certain brain regions that have specific functions that give rise to complex emotions. " Another scientist, Professor Nick Bostrom as Director of Oxford University Future of Humanity Institute said, we do not have to think perspective to fully understand what love is. There are evolutionary, sociological, phenomenological (philosophical approaches and qualitative research methods) and humanistic perspectives that offer important insights.
