Boosting Brains With Ultrasound

Ultrasound — sound waves with a frequency greater than the upper limit of the human hearing range — may heighten sensory perception in humans by modifying brain activity, according to new research by scientists from the Virginia Tech Carilion Research Institute and published online Jan. 12 in Nature Neuroscience.

Researchers focused the ultrasound on the brain's cerebral cortex, which processes sensory information, and demonstrated significant improvements in sensory perception likely due to the ultrasound's effectiveness in altering human brain activity.

Scientists involved in the study said that further research of ultrasound may lead to noninvasive treatments for a range of neurodegenerative, psychiatric and behavioral disorders.
