What if sound could heal?
Sound has been harnessed for uses from medical imaging to SONAR. Now, scientists are exploring how ultrasound can be used to treat conditions as varied as addiction and depression and brain cancer. Wynn Legon explains the evolution of focused ultrasound and how his lab is contributing to the growing list of ways the technology can benefit our health.
More About Wynn Legon
Wynn Legon is an assistant professor at the Fralin Biomedical Research Institute at VTC in Roanoke. His lab studies the use of low-intensity focused ultrasound (LIFU). LIFU is an emerging form of noninvasive neuromodulation that uses mechanical energy to affect neuronal activity. The technology combines high spatial resolution with deep focal lengths providing unprecedented noninvasive access to the human brain. The enormous potential of LIFU stems from the ability to focus it through the intact skull to a millimeter-sized spot virtually anywhere in the brain. This makes it a powerful alternative to both invasive neurosurgical procedures and other noninvasive brain stimulation techniques.
