The Neuroscience of Falling in Love

When falling in love, the brain releases neurotransmitters like dopamine and norepinephrine, leading to feelings of pleasure, reward, and motivation. The sympathetic nervous system, responsible for the fight or flight response, becomes activated in the early stages of love. Love evolves and changes over time, with stress hormones like cortisol decreasing and love becoming a buffer against stress. Hormones like oxytocin and vasopressin play a role in forming deep connections and promoting monogamous relationships. Genetic factors, including oxytocin receptor genes, can influence our ability to empathize and desire relationships. Love is a complex and universal phenomenon, influenced both by biology and culture.
