Heart aflutter? Can't get that special someone out of your head? Could it be love, or is it just a chemical cocktail of dopamine and serotonin flooding your brain?
“Love is the result of chemical changes in the brain when we meet someone and feel that connection,” UW Medicine neuroscientist Larry Zweifel said. “There are long-term changes in our brain when we connect with someone that links us to those individuals, sometimes for life. I think that’s tremendously fascinating.”
“In terms of establishing desire, chemically speaking, first impressions are crucial,” Zweifel said. “It’s how the brain processes those initial responses and that social feedback that determines whether or not we’ll engage with another individual again in the future, or whether we will do our best to avoid them.”
Zweifel explained that a lack of those chemicals might leave someone feeling sad on Valentine’s Day. Chemicals can also show why people impulsively love and fight.“People can be filled with a sense of dread as that date approaches, and there are many reasons why someone might feel averse to the thought,” Zweifel said. “Holidays that come with high expectations can be a major source of stress.”
