Ep.11 - Do This For A Healthy Brain
from Frequency 528 — Real People. Real Connections. Hosted by Frequency Sound 528
I sit down with my mother Lynn and my brother-in-law and talk science. He shares some of the studies he’s been apart of and educates us on one of the most effective tools for a healthy brain. Dr. Jay M. J. R. Carr (Researcher) Dr. Jay Carr is a Postdoctoral Fellow at the University of British Columbia (Okanagan Campus). His work focuses on the mechanisms governing blood flow to the brain and how it adapts to various physiological stresses. Primary Research Focus: He investigates cerebrovascular reactivity (CVR)—the ability of brain blood vessels to dilate or constrict in response to changes in carbon dioxide (𝐶𝑂2) and oxygen levels. Key Findings (2025–2026): Hypoxic Vasodilation: His research details how the brain maintains oxygen delivery during low-oxygen states (hypoxia) through mechanisms involving nitric oxide and potassium channels. Exercise and Brain Health: He has explored how different modes of exercise, such as interval training versus continuous aerobic exercise, impact cerebral endothelial function. Lactate Metabolism: Recent 2025 studies involve how the brain preferentially uses lactate for fuel during intense exercise or infusion, which may help preserve glucose for other brain functions.
