Your brain does a good job of protecting itself from bacteria. Unfortunately, that also means it's a pro at blocking life-saving medicine.
Dr. Vibhor Krishna is a surgeon-scientist investigating a procedure that could deliver medicines to the brain without a single incision required.
His main obstacle? The brain itself, which is protected by a blood-brain barrier that holds off numerous dangers such as infections and bacteria. The blood-brain barrier also walls out medicines meant to fight diseases.
In this video, Krishna — a neurosurgeon at the Wexner Medical Center and member of Ohio State’s Chronic Brain Injury Program — explains how focused ultrasound opens the blood-brain barrier and why it could mean powerful results.
