About This Lesson
Elisa Konofagou is using ultrasound waves to break through what is known as a "blood brain barrier". This is a barrier that protects the brain, but it also interferes with some brain disease treatments. Find out why ultrasound technology could become part of the treatment process for cancer, Alzheimer's and Parkinson's disease in this episode of Innovation Nation with Miles O'Brien.
