This episode serves as a sort of “Dopamine Masterclass”. I discuss the immensely powerful chemical that we all make in our brain and body: dopamine. I describe what it does and the neural circuits involved. I explain dopamine peaks and baselines, and the cell biology of dopamine depletion. I include 14 tools for how to control your dopamine release for sake of motivation, focus, avoiding and combating addiction and depression, and I explain why dopamine stacking with chemicals and behaviors inevitably leads to states of underwhelm and poor performance. I explain how to achieve sustained increases in baseline dopamine, compounds that injure and protect dopamine neurons including caffeine from specific sources. I describe non-prescription supplements for increasing dopamine—both their benefits and risks—and synergy of pro-dopamine supplements with those that increase acetylcholine.    Thank you to our sponsors: ROKA - https://www.roka.com -- code "huberman" InsideTracker - https://www.insidetracker.com/huberman  Headspace - https://www.headspace.com/specialoffer    Logitech Event - Rethink Education: The Biology of Learning Thursday, Sept. 30 at 12pm PT / 3pm ET Sign up here: https://info.logitech.com/ReThink-Education.html    Support Research in Huberman Lab at Stanford: https://hubermanlab.stanford.edu/giving   Our Patreon page: https://www.patreon.com/andrewhuberman    Supplements from Thorne: http://www.thorne.com/u/huberman    Social: Instagram - https://www.instagram.com/hubermanlab  Twitter - https://twitter.com/hubermanlab  Facebook - https://www.facebook.com/hubermanlab  Website - https://hubermanlab.com  Newsletter - https://hubermanlab.com/neural-network    Links: Review on Dopamine - https://doi.org/10.1038/  s41583-021-00455-7  Cold Exposure & Dopamine - https://link.springer.com/article/10.1007%2Fs004210050065    Timestamps: 00:00:00 Introduction & Tool 1 to Induce Lasting Dopamine 00:04:48 Sponsors: Roka, InsideTracker, Headspace 00:09:10 Upcoming (Zero-Cost) Neuroplasticity Seminar for Educators 00:09:58 What Dopamine (Really) Does 00:15:30 Two Main Neural Circuits for Dopamine  00:18:14 How Dopamine Is Released: Locally and Broadly 00:22:03 Fast and Slow Effects of Dopamine 00:25:03 Dopamine Neurons Co-Release Glutamate 00:28:00 Your Dopamine History Really Matters  00:30:30 Parkinson’s & Drugs That Kill Dopamine Neurons.
