An update on brain zapping

This 2017 general-audience article entitled Ultrasound for the brain provided a hyped update on brain zapping:

“Ultrasound could potentially treat other movement disorders, as well as depression, anxiety and a host of intract­able neuropsychiatric disorders..

This could be a breakthrough..

Researchers hope one day to help people with neuropsychiatric conditions by repairing or resetting the relevant neural pathways..

The potential advantages, especially for deep brain areas, are huge..”

Though not the main thrust of the article, another potential use of ultrasound would be to activate drugs delivered to a specific area, as this image portrays:


Vanderbilt University was again at the forefront of brain zapping, as noted in What’s an appropriate control group for a schizophrenia study? for example. I hope the disclaimers for subjects participating in Vanderbilt’s brain-zapping studies made it clear that:

“At high intensities, such as those used to relieve essential tremor, ultrasound’s effects are largely thermal: the tissue heats up and cells die.”
