The Scientist Who Scans Fathers' Brains: Parenthood Shrinks Your Brain, And Drops Testosterone 25%!
Descripción del Episodio
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.

In The Dark
By shows
In the Dark, hosted by Madeleine Baran, is an award-winning investigative-journalism podcast that started in 2016. Its first season looked at the mysterious abduction of Jacob Wetterling in rural Minnesota and the lack of accountability that sheriffs face when they fail to solve cases. Season 2 examined the case of Curtis Flowers, who was tried six times for the same crime. In 2020, In the Dark released a special report on the coronavirus pandemic in the Mississippi Delta. In 2023, In the Dark joined The New Yorker and in 2024, it released “The Runaway Princesses,” a four-part series that asks why the women in Dubai’s royal family keep trying to run away. Season 3, released in 2024, asked why no one was punished for the killings of twenty-five civilians in Haditha, Iraq. In the Dark won the Pulitzer Prize for audio for Season 3. The podcast is a three-time Peabody Award winner and, in 2019, became the first podcast to win a George Polk Award, one of the top honors in journalism.
