All mammalian species appear to release oxytocin during lovemaking, a chemical reaction that can temporarily deactivate the defense systems that would otherwise make the process of mating impossible. But here’s the key: In species that mate for life and form strong, enduring bonds between parents and offspring, there are lots of receptors for oxytocin in the reward center of the brain—in the nucleus accumbens region that is a critical part of our social engagement system and the parenting brain.
所有哺乳类动物在做爱过程中都会释放催产素,这种化学反应可以暂时解除防御系统,否则会使交配过程变得不可能。但关键是:在物种厮守终身,形成强大的父母与子女之间的持久的联结的过程中,大脑的奖励中心伏隔核区域——我们社会参与系统和育儿的大脑是一个关键的一部分,存在大量的催产素受体。
