Editors note: This is part 2 of our 2 part episode with Professor Jack Feldman, don’t forget to catch our first episode here.
The Most Important Thing
We continue our conversation with Professor Jack Feldman on how he revolutionized our understanding of the neural control of breathing. We dived deeper into the topic of breathing and how it has the ability to change our emotional state. I also get to run a few yoga teachings on the breath by Jack to see how they align (or don’t) with his scientific understanding.
About the Guest
Jack Feldman is a distinguished Professor of Neurobiology, he also holds a Ph.D. in Physics and is currently teaching at UCLA.
His contributions to understanding the mechanisms of breathing and sighing include the pre-Bötzinger complex and demonstrating the essential role in generating respiratory rhythm in fetal, neonatal, and adult mammals. Jack Feldman’s influence is evident in numerous highly cited reviews, textbooks, and lectures. He was awarded the prestigious Hodgkin, Huxley, Katz Prize of The Physiological Society.
Episode Overview
In part two of this episode, Professor Jack Feldman shared his thoughts on living through the polio epidemic and broke down of the importance of a vaccine. Besides that, he also shared how his study finds that breathing could affect cognitive functions positively.
Jack also took a few moments to highlight the differences in breathing between animals and humans in this episode.
My Favorite Quotes
“I've been wearing a seatbelt for ever since they became available. I've yet to get in a serious car accident. So you could argue why bother wearing a seatbelt? Well, you wear a seatbelt because the consequences of the rare possibility you get in an accident.”
“if you weigh that against the possibility that the vaccine does something negative right now, that data is extremely small. I wouldn't say zero. It's extremely small. And certainly if the odds are 99.999999 in favor.”
“One of the ways that the brain consolidates it's information is then when things repeat, it strengthens the connections between neurons.”
“If you're less anxious, you're likely to have a longer lifespan if you could maintain it.”
“When we think about how breath could be influencing higher function, cognition, or emotion, the signals that are related to breathing can arrive in the brain by a variety of pathways. Every time you expand your lungs, there are receptors in your lungs that become activated. They send signals up into the brainstem, through the vagus nerve.”
