Can a Hormone Explain Why Humans Love Each Other?
Some researchers think they have zeroed in on an explanation, oxytocinSome researchers have been trying to understand why mothers love their children: When it comes to biological mechanisms of empathy, scientists are particularly interested in oxytocin, the so-called “love hormone.” High oxytocin levels predict sensitive parenting, but it isn’t clear how the oxytocin-related gene might generate variation in empathy and parental behavior. One possible explanation is epigenetic changes to the gene — a way of altering gene function without changing the actual DNA sequence. Specifically, “DNA methylation” — the addition of a chemical group called the “methyl” group at specific locations — in the oxytocin gene (called OXT) has been associated with personality traits and brain structure in humans. This raises a question: can methylation of OXT influence empathy in Read More ›
