Technology For Brain Cooling Unlikely To Help Trauma Patients

Technology For Brain Cooling Unlikely To Help Trauma Patients
Attempts 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. The shielding effect, created by large quantities of warm blood that continually perfuse........Go to the Neurology news blog (Added on 8/20/2006 2:10:00 PM)
