Jack Feldman is a Brooklyn, NY native with his PhD in Physics and is a Distinguished Professor of Neurobiology at UCLA.  According to my friend and previous guest Andrew Huberman “Jack is the world leader in all things breathing” so who better to talk to about this amazing gift of breath than Jack.Jack discovered an area in the brain stem that is responsible for the rhythm of breath which he named the pre-Botzinger complex.  He is a world leader into the discovery of the answer to this simple question…“How is the very basic rhythm of breathing generated?”In this episode we explore Jacks journey to answer this simple sounding question and he shares a lot of valuable information and insights into how our respiration impacts our health and optimal performance….including how the breath prepares the body for exercise before it even begins…why HIIT works…and very interesting findings with episodic hypoxia training.I really enjoyed talking with Jack and I hope you find value in our conversation.  Thanks as always for tuning in and supporting the show!Topics covered:the physics journey of space and timepivot to study the breathphysiology of breathhow is the very basic rhythm of breath generatedpre botzinger complexsync of fireflies in nature like our breath neural activationevolutionary look at breathembryology and breathanatomy of breathexercise activate active expiration oscillatorHRV and how variance required for optimal healthbreathing rhythm found throughout entire brainlab mantra “you can’t do anything interesting if you’re afraid of failing”time scale of breath and learningsleep apnea science and treatmentpower of napping and mindfulness on our healthbreathing and emotion researchhow breathing can interrupt depression patternsthe importance of oscillations in communication across the brainrespiratory rate variance is keycellular respirationwhy HIIT is effectivethe performance benefits of episodic hypoxiaFind Jack:Linkedinhttps://www.linkedin.com/in/jack-feldman-bb493639/Google scholarhttps://scholar.google.com/citations?user=7VU42UMAAAAJ&hl=enAndrew Huberman and Jack Feldman convo on instagramhttps://www.instagram.com/tv/CEICXI0Hf0u/?hl=enThis was a live recorded conversation all about the neuroscience of breathing, its relationship to emotion, depression, opioids, and a lot more.
