DARPA Seeks Ultrasound-Enhanced Helmets for Soldiers

Posted October 05, 2010 12:00 AM by baumah

Using a soldier's helmet to control his or her thoughts or moods may seem like a bad conspiracy theory, but it could turn into reality with the help of a transcranial pulsed ultrasound technology. Dr. J Tyler, an Assistant Professor at Arizona State University, has been working with transcranial pulsed ultrasound to stimulate different areas of the brain without requiring surgery. The results could have effects both on the battlefield and beyond it.

Deep brain stimulation (DBS) has been used for treating a variety of brain dysfunctions including epilepsy, Parkinson's disease, chronic pain, depression, and anxiety. "Scientists have known for more than 80 years that ultrasound can influence nerve activity," Dr. Tyler explains. In 1st century AD, a Roman physician named Scribonious Largus treated patients with headaches by placing electric torpedo fish on their forehead to relieve some of their pain.

According to Tyler, two of the biggest obstacles are attaining high spatial resolution and deep penetration. Currently, DBS techniques generally require surgically implanted electrodes to obtain a high resolution and sufficient penetration to be effective.

Thanks to a new grant from the Defense Advanced Research Projects Agency (DARPA), however, Tyler is working to develop applications specifically for soldiers. Stimulating different parts of a soldier's brain could allow military personnel to increase alertness, alleviate stress, and possibly reduce the effects of a traumatic brain injury. So far, Tyler's team has developed working and conceptual prototypes of ballistic helmets embedded with ultrasound transducers and microcontroller devices.

Do you have a link to his work?

Yes, a link would be helpful.

Also, "increase alertness, alleviate stress, and possibly reduce the effects of a traumatic brain injury" is a FAR cry from controlling his or her thoughts or moods.

This editor has added the author's references to the "Resources" section in the original blog entry. My apologies for the omission. The blog-entry's title has been changed as well.

Why does this subject bring to mind the old Memorex commercial of the opera singer shattering a crystal glass, and the announcer asking, "Is it real, or is it Memorex?" Bursting brain cells does not sound like a friendly thing to do to one's own soldiers....

As a combat veteran, albeit an old one, the concept of altering my awareness on the battlefield seems a scary one. I wonder how they plan to enter the actual test phase.

Anybody remember the old "chinese water torture"? Yes, there are things that can probably make you stay awake...

AFAIK brain electrical activity is complex, coordinated across brain regions/structures, and poorly understood. When it comes to highly trained fighters, the level of coordination is expected to be even tighter, your life depends on it. Along come the torturers, with the bogus pretext that you can "improve" on this by bombarding one or more regions of the brain with repetitive pulse trains. Doh! There is not afaik any data to support the claim of benefits to healthy brains. The therapies they hope to mimic (DBS, VNS) cause neural damage in the process, even though they do (sometimes) provide some benefits to desperately ill people. You might as well give chemo or radiation to people who don't have cancer.

I'm betting these helmets will never see action. They will be used to experiment on some unfortunate soldiers, maybe develop some weapons or torture apps, and that is that.

Defense Advanced Research Projects Agency (DARPA), has abandoned work with Tyler of Arizona State University in his efforts to effect full brain control of soldiers.

It was determined that controlling the brains of the soldiers was really a waste of time, and it was more cost effective to just cut their heads off and replace them with new brains.
