Love: a qualitatively, not just quantitatively, different neurological activity than liking.

“Neurologists have found that, when you see your beloved, parts of

your brain ‘light up’. The heart has nothing to do with it,

suggesting St Valentine’s Day cards should be emblazoned, not

with images of the heart, but of the medial insula.

A study by Professors Semir Zeki and Andreas Bartels of

University College, London, to be published in the journal

NeuroReport next month, confirms that being in love is

physically different from merely liking someone.

Physical effects of this brain activity may account for the

traditional sensations associated with love, including euphoria,

butterflies in the stomach, love sickness and love addiction.” Guardian
