How does "love" react in biology?

Many people to "love" simply summarized as the secretion of dopamine, this simple idea, in fact, ignore the love is a systematic project! In fact, love is a fairly complex and random process, and this process is no less than a complex analysis of the gambling odds process. So, will there be love with me how I am feeling, and when you really understand what is "love" after this perception will be more profound.

The above figure is a foreign scientist in the system analysis, the impact of love four modules. The real "love of the process" is the interception of these situations. The four modules are:

1. Sexual behavior: this is the inevitable factor in the birth of love. In the words of the analyst, is involved in "unbearable nerve itch";

2. Romance: Scientists will be summarized as - emotional, which is the formation of "love" in the process of accelerating the development of factors. Such as science and technology to find new love when the early obsession and excitement.

3. Additional factors: trust and reliability. Yes, you are not wrong, this is actually the formation of love "additional factors." This can also explain why the lightning romance will produce the reason. Trust and reliability are in the process of love, and gradually formed.

4. Reward mechanism: this part, the human brain will continue to release dopamine, people feel ecstatic. This is what many people experience - the feeling of love. So many people simply think that love is the process of secretion of dopamine. Of course, this system in the human brain under the control of the rational release of dopamine and other substances. This is a system related to the motivation cycle, but not just the cause of "love". Just as you eat chocolate when the happiness, but also through the system secrete, but it is not love.

Although the system is composed of four parts, but how do they work? That is how love is how to produce it? In fact, the formation of love is a result of a combination of chemical systems and vagaries. In this process, dopamine acts as "a sense of love", but how to secrete dopamine, you need the system of the other three factors in the comprehensive decision.

For example, when the heterosexual hug or eat a candlelight dinner, dopamine will be released. Or, when you see each other dressed more sexy, dopamine will be released. This system is constantly releasing the process of dopamine, and gradually form a "love". And this system of additional factors, in fact, as early as in the maternal and child period formed. Such as "calm and trust", is formed during the baby's treatment during feeding and taking care. And a deeper sense of happiness and satisfaction, in fact, is formed under the action of this system.

When the body reacts internally due to these chemical factors, the vagus nerve will be "driven". These vagus nerve actually attached to the brain and heart, by stimulating the facial muscles to form "expression". These expressions allow us to engage with our partner "eye contact and facial expression synchronization." Not only that, it can also adjust the muscles of your ears! To help you concentrate and pay close attention to the voice of the companion to reduce the background noise involved.

Here we know that love is mainly an organic or biological process. But the problem has come, this process because there are too many uncontrollable factors, making the "monogamy and true love" between the more difficult to one by one correspondence. This system is also explained, some people will fall in love reasons.

And this also explains why the love from the honeymoon will gradually reduce the passion, but also explain why marriage is a social contract. In the absence of the initial passion, we need more love in the formation of the four modules continue to create love power, to maintain the long-term marriage.
