Love Science

As today, is Valentine's Day (Happy Valentine's Day!) it seems appropriate to focus on the emotion, love. Obviously there are different intensities to the feeling, there is the milder form of admiration, want, or full on passionate lust, however it seems that all these different kinds, have the same basic origins.

Love, is not a very well understood emotion and it thought to have a basis in evolution. As human infants are the only organism to completely rely on their parents for such a prolonged period of time (18 years) it was seen that love helps to promote parental support and form closer knit bonds, between child and parents.

The neurological aspects of  love can be found via carrying out neurological studies. The chemicals involved in the feeling of love are: testosterone,oestrogen  dopamine, noradrenaline, serotonin, oxytocin and vasopressin. All of these drugs help to display the characteristics of sexual behaviour, the attractive portion of a relationship and the want to form long term bonds.

So what's your definition of love?

Explorer Fact: Biologist Jeremy Griffith defines love as being unconditional selflessness.
