Measuring Brain Blood Flow and CO2 in Real Time—Why This Changes Concussion Recovery with Dr. Nate Keiser (Part 2) | E58

Your autonomic nervous system isn’t “just stressed,” and dysautonomia isn’t a single, one-size-fits-all box. We zoom out from symptom labels and zoom in on mechanisms: how the brain senses the body, builds an internal map, and then uses that map to regulate heart rate, blood flow, digestion, sweating, temperature, and even hormone feedback loops.

We talk neurocardiology in plain language, including why the brain controls the heart beat by beat, how the cerebellum helps automate autonomic function, and why a disconnect can show up as tachycardia or rhythm issues. We also dig into the insular cortex and interoception, including why some people feel a pounding heartbeat even when their heart rate is normal and what that can reveal about nervous system signaling.

From there, we connect functional neurology with acupuncture and Chinese medicine concepts, focusing on objective feedback like pulse shifts, sensory tingling, motor twitches, and vasomotor changes. We also get real about treatment: why “try this medication” is common, how paradoxical responses can happen (even when blood pressure looks better), and why measuring outcomes like cerebral blood flow can change the entire plan. If you’re dealing with POTS, post-concussion syndrome, or chronic autonomic symptoms, you’ll leave with a clearer way to organize your timeline, ask sharper questions, and pursue strategies that match your physiology.
