In a world-first study, a team of Australian scientists investigated the link between the human brain’s behavioural activation system (BAS) and romantic love and decoded why “love is blind”. It is well known that romantic love changes the brain, releasing the so-called love hormone oxytocin, responsible for the euphoria we feel when falling in love.

Now, researchers from the Australian National University (ANU), University of Canberra and University of South Australia have measured how a part of the brain is responsible for putting our loved one on a pedestal in that first flush of romance.
