Contestants have five minutes in an fMRI to love someone ‘as hard as they can’

Can you look inside the living brain and tell what someone is feeling? For the first time in history we have fMRI – a technology that promises to show the neurochemical traces of joy, rage, love and hate, as they cascade through the brain. Filmmaker Brent Hoff enlisted the Stanford Center for Cognitive Neurobiological Imaging to hold the world’s first ever ‘love competition’. Seven contestants had five minutes in an fMRI machine to love someone ‘as hard as they can’. The idea that love can be measured may seem deeply unromantic: the results were anything but.
