“We have this amazing opportunity to probe the brain non-invasively that we didn’t have before. We hope ultrasound becomes a new tool that neuroscientists can use to map the brain or apply to their specific questions and translate this to efficacious clinical therapies.”

 

Using sound waves to treat brain disorders

Can focused ultrasound cure addiction and eliminate pain? 

Wynn Legon, Ph.D., has been at the forefront of the use of focused ultrasound to modulate human brain activity for a decade. He co-authored one of the seminal papers on use of the technology in humans, which showed ultrasound aimed at a specific area of the brain selectively changes neuronal activity that can boost sensory discrimination performance. It was the first demonstration that the technology can modify human brain activity to enhance perception. Legon's research at the Fralin Biomedical Research Institute will focus on using low-intensity focused ultrasound to treat addiction and pain. HIs lab employs several techniques including electroencephalography (EEG), electromyography (EMG), transcranial magnetic stimulation (TMS), functional magnetic resonance imaging (fMRI), behavioural testing, empirical acoustic testing and computer modelling.  ​
