Women obviously go through many changes to their bodies and their minds when they become mothers.  But what about fathers?  Although moms have been studied extensively, few people have paid any attention to what happens to men when they become dads.   Do they go through any physical changes at all?  Do they also experience hormone surges and shrinking brains like women do (yes mom and dads, your brains got smaller). Do they also suffer from depression and anxiety?   Dr. Darby Saxbe has dedicated her career to studying fathers, and in her new book, Dad Brain, the New Science of Fatherhood, she reveals things about fathers that are as surprising as they are dramatic, discoveries which could have enormous impact on how society views dear old dads, and their role in raising children.

For five seasons now, I've been delighted to explore the wonders of the brain with my guests as well as with you, my listeners. Podcasting is fun and enlightening, and I've heard from many of you that it's been helpful as well as informative. It's also time-consuming, especially given my busy practice and my administrative duties as department chair. That's why the podcast is going on hiatus before Season 6 begins to let me attend to some of my other work for a while. I hope you take this opportunity to catch up on episodes you may have missed over the past five seasons. There are more than 100 fascinating guests and topics to explore at your leisure. From anger to dance moves to stem cells, these episodes cover a fascinating range of topics, all centered on our most intricate and complicated organ, the brain. See you in season 6! ###  For more information, transcripts, and all episodes, please visit https://thisisyourbrain.com   For more about Weill Cornell Medicine Neurological Surgery, please visit https://neurosurgery.weillcornell.org

Humans are born with billions of neurons that need connecting – and how those synapses develop helps determine how our brains will work. There is ample evidence that a loving, nurturing environment in infancy and early childhood provides the most fertile ground for brain development. Isabelle Hau, executive director of the Stanford Accelerator for Learning, explains why a well-loved baby or child simply learns better than a neglected one, and how our contracting social circles endanger our kids. Plus… the mystery of why average IQs rose for decades, until recently. Are technology and isolation affecting our intelligence?

The past 30 years have produced an epidemic of obesity -- mostly because evolution did not prepare us for so many calories and so little physical activity. Dr. Louis Aronne, a leading authority on obesity, explains how a period of caloric excess can damage the neural connections that manage your metabolism, throwing your weight regulation out of whack. More importantly, he talks about the new drug that tackles obesity at two different hormonal sites and promises to become an actual "weight loss pill."

What makes us happy? The warm feelings of closeness that we have with family and friends are rooted in the neurochemical oxytocin – the love hormone, if you will. Oxytocin facilitates social engagement, encourages bonding, and just makes us feel happier. My guest today, neuroscientist Paul Zak, has done decades of research into the role of oxytocin and discovered that this feel-good chemical motivates us to engage with others. Not only that, but immersing ourselves in social circles, among people who are nice to us, increases oxytocin and improves our mood. (High stress, on the other hand, inhibits oxytocin and makes us feel unhappy.)  Find out how to harness the power of oxytocin to live a happier, healthier, life.  For more information, transcripts, and all episodes, please visit https://thisisyourbrain.com For more about Weill Cornell Medicine Neurological Surgery, please visit https://neurosurgery.weillcornell.org

Candace Pert discovered the opioid receptor, created a drug to stop AIDS in the brain, and identified stress as a cause of disease. She also inadvertently unleashed the overdose epidemic, got herself kicked out of the NIH, and was denied credit for much of her work. Pert was a trailblazing yet mercurial neuroscientist, a woman who made her male boss famous but has been largely forgotten herself. She was also a rebel, a workaholic... and a bit mad. In this episode, Pamela Ryckman, the author of a new biography of Pert, reveals some of the wilder tales about her and explains why she remains largely unknown even though her discoveries were truly life-changing.

We will never create true artificial intelligence (if we really want that) until we know more about how the human brain works. Tech entrepreneur and author Max Bennett explains how AI learns, where it falls short, and how it stacks up against our own intelligence. As it turns out, what's easy for humans is hard for AI, but AI is better at doing some things that are quite hard for us. Mostly, what AI teaches us is just how remarkable the human brain is - it is much better at continued learning than AI is, and it requires less input to come to conclusions. But... Can we trust it?  For more information, transcripts, and all episodes, please visit https://thisisyourbrain.com For more about Weill Cornell Medicine Neurological Surgery, please visit https://neurosurgery.weillcornell.org
