One of my favourite scientific advances in the last 20 years is the ability to take pictures of the brain and its circuitry in action, and what this continues to teach us about how we are wired and therefore why we do what we do.
Anthropologist Helen Fisher is a leader in this area and has extensively studied what happens in the brain as it relates to love. She has differentiated 3 types of love, that each have their own areas of the brain that light up:
1. Sexual attraction or lust – Fisher describes as more like an actual “drive” like hunger, and just like hunger is required for your survival (if you don’t eat you will die). Sexual attraction or lust, (driven by estrogen and testosterone) is required for the survival of the human race. You can have a number of people who you are sexually attracted to but in humans we usually put it together with at least one of the other types of love.
