Is love just chemical trickery?

摘要

There is a reason most of us sigh into our drinks when Cole Porter croons, "What is this thing called love?" We understand his befuddlement all too well. (And let's face it: if a man about town like Porter couldn't figure out this whole love thing, what hope is there for the rest of us mere mortals?) That's why it is encouraging to know that in the past two decades social neuroscientists have been diligently working to unravel the mysteries of love - including the phenomena of attraction, monogamy and the parent-child bond - using techniques such as brain imaging, genome-wide association studies and transgenic animal models.
