The Brain in Love

Why do we crave love so much, even to the point that we would die for it? To learn more about our very real, very physical need for romantic love, Helen Fisher and her research team took MRIs of people in love — and people who had just been dumped.

This talk starts slow but soon the information becomes very interesting. More about the Science of Love on the BBC, thanks Dr Confabula
Key Points from the science of love:

  • There are three phases to falling in love and different hormones are involved at each stage
  • Events occurring in the brain when we are in love have similarities with mental illness
  • When we are attracted to somebody, it could be because subconsciously we like their genes
  • Smell could be as important as looks when it comes to the fanciability factor. We like the look and smell of people who are most like our parents
  • Science can help determine whether a relationship will last

The last key point I am not so sure!
