Technology For Brain Cooling Unlikely To Help Trauma PatientsAttempts to cool the brain to reduce injury from stroke and other head trauma may face a significant obstacle: current cooling devices can't penetrate very deeply into the brain.
Researchers at Washington University School of Medicine in St. Louis used rats to validate a "cold shielding" effect of blood flow that they previously predicted theoretically.
