What actually happens to your brain, and how fast or slow do you age when you become a parent? Dr. Darby Saxbe reveals the surprising science of the "parental brain" and how fatherhood physically reshapes a man's mind, why dads lose grey matter, what really happens to testosterone, and why the "dad bod" might be nature's design. Dr. Darby Saxbe is a professor of psychology and a leading researcher on the neuroscience of parenthood. She is the founder and director of the NEST (Neuroendocrinology of Social Ties) Lab at the University of Southern California, where her pioneering work studies how the transition to parenthood changes the brains, hormones and relationships of both mothers and fathers. Her research has reshaped how scientists understand fatherhood, men's mental health, and what it really takes to raise a child.
