Episode notes

Neurons are fascinating cells that communicate with each other through electrical and chemical signals. The cell body and axon are the critical parts of a neuron, with dendrites acting as the connections between cells. Neurons resemble tree branches or bird toes. They regulate the flow of ions like magnesium and sodium. It's an exciting mix of electricity and chemicals in the brain!

Hi! I’ve been in the hospital with pneumonia! But enjoy this banger of an encore about: 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?"
