Parenting expert 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 Lab at the University of Southern California, and is also the author of ‘Dad Brain: The New Science of Fatherhood and How it Shapes Men's Lives’.

◼ Why the "dad bod" may signal a more attentive hands-on father
◼ Why men experience postpartum depression
◼ Why raising a child was never meant to be done by two people alone
