艾里森说：“女人的一生中，没有什么时候比照顾一个孩子更需要聪明头脑。人类的大脑一直在生产细胞，这些细胞只有被利用才更有可能存活下来。‘充满感情的’、‘有挑战性的’和‘新鲜的’经历会让这些神经细胞活跃起来，而这些词用来形容‘怀孕’这件事可再合适不过了。”
Miss Ellison said: "There is no other time in a woman's life when she needs to be quite as smart as when she is looking after young children. "The human brain creates cells throughout life, cells that are more likely to survive if they're used. "Emotional, challenging and novel experiences activate these new neurons, and what adjectives better describe having children?"
