Revolutionary Study Links Heartbeat to Brain Blood Flow

12/22/2025

Summary

Story summary

Researchers led by pediatric neurosurgeon Michael Egnor show that brain blood flow synchronizes with the heartbeat, suggesting new therapies.
They collaborated with engineers to uncover design principles and identified a cerebral Windkessel system formed by the skull, brain, and vessels.
The Windkessel system uses filters to maintain steady flow and prevent capillary damage.
The work illustrates theory of biological design (TOBD) in medicine and parallels Stuart Burgess on optimal design.
