About this episode

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 sleep, focus, happiness, depression, anxiety, what chemicals drive us to get off the couch, ADHD, the microbiome, and so much more of what goes into making our noggins work they way they do.
