Serotonin! Dopamine! Norepinephrine! Neurotransmitters: what's their deal? Dr. Crystal Dilworth, aka Dr. Brain, stops by to have a spirited discussion about how chemical messengers change our moods and behaviors. We chat about depression, anxiety, what chemicals drive us to get off the couch, how antidepressants work, ADHD, addiction, the microbiome, new habits, quitting smoking, starting meditation, Oreos vs. cocaine, SSRIs vs. SNRIs, what it's like to hold a human brain in your hands and if she would donate hers to science. Also: what's up with "lizard brains?"
