"Over the last decade, we've learned more about the transformative power of parenthood-biologically, psychologically, and socially-than ever before. But while the experience of motherhood has attracted well-deserved attention, fatherhood has remained overlooked and, often, misunderstood. Now, in Dad Brain, field-leading psychologist Darby Saxbe, PhD, explains how becoming a father changes men, from their bodies and brain architecture to their hormones and sense of purpose. Inspired by her relationship with her dad, Saxbe has studied fathers and families for over twenty years. In her first book, she takes readers behind the scenes of her new research and around the world, from hunter-gatherers in the Congo to contemporary suburban dads, and into her pioneering studies of how parenthood shapes men's brains and lives."
