This is Your Brain on Hormones

After reading something that said her menstrual cycle changes her brain each month, Senior Correspondent Molly Webster goes on a reporting mission to see if that’s true, and, if so, how. This journey into sex hormones and the brain involves females and males, and exacting self-experimentation. It gets into PTSD, and ends with a new twist on self-care (hint: it’s biological). And, it starts to reveal a sneaky truth: that each one of us is at the mercy of a crashing sea of chemicals inside of us – those things we call hormones. Special thanks to Emily Jacobs, Laura Pritschet (https://www.pennlinc.io/team/laura-pr...) , Pavel Shapturenka, and Dr. Catherine Woolley.
