Nick talks to neuroscientist Dr. Margaret McCarthy, whose lab at the University of Maryland studies the origins and mechanisms of sex differences in the brain, the endocannabinoid system, and neural basis of animal behavior. They discuss: the nature of sex differences observed in the mammalian brain, including differences in the susceptibility to various diseases and disorders of the brain; differences in juvenile play behavior in males vs. females, and how these can be altered by sex hormones and cannabinoids; sex differences in brain development that lead to sex differences in behavior; how the endocannabinoid system influences brain development and behavior; how cannabis use during pregnancy may influence brain development.Support the showSign up for the free weekly Mind & Matter newsletter:[https://mindandmatter.substack.com/?sort=top]Learn how you can further support the podcast: [https://mindandmatter.substack.com/p/how-to-support-mind-and-matter]Become a Premium Subscriber to access full content library, including full premium episodes:[https://mindandmatter.substack.com/subscribe?utm_source=menu&simple=true&next=https%3A%2F%2Fmindandmatter.substack.com%2F]Try the Lumen device to optimize your metabolism for weight loss or athletic performance.
