The Science of Love

We fall in love with our heads, not our hearts.  Neuroscientist Larry Sherman, Ph.D., joined us to share the chemical reactions that take place and cause us to feel attraction.

  •  How do people first become attracted to one and other? Visual  stimuli are important, but so is smell and so are the levels of testosterone and estrogen at the time people meet-- this is mostly about lust.
  • What happens to the brain when we are in that stage of love where we just can't stop thinking about the other person?  This is driven by three chemicals in the brain called monoamines; each has its own set of effects on our concentration, mood, and heart rate.  They drive the behavior that keep us thinking about the other person, but also increase our heart rates and make us sweat when we see the person we are in love with.
  • Does this happen throughout life? Do older people get that same "rush" of neurochemicals?  They do, but not to the same degree, mainly becasue of homonal changes.
