Non-invasive brainwave technology can potentially cut post-traumatic stress

The technology works through resonance between brain frequencies and the acoustic stimulation, where the brain is supported to make self-adjustments towards improved balance and reduced hyperarousal. It requires no conscious or cognitive activity.

  • The new technology aims to reduce the effect of post traumatic stress in an individual.
  • It can reduce many post-traumatic symptoms, including insomnia, depressive mood and anxiety.

Researchers have developed a non-invasive brainwave mirroring technology that can significantly reduce symptoms of post-traumatic stress, especially in military personnel.

Post-Traumatic Stress Disorder (PTSD) is a disorder characterised by failure to recover after experiencing or witnessing a terrifying event.

The symptoms include insomnia, poor concentration, sadness, re-experiencing traumatic events, irritability or hyper-alertness, as well as diminished autonomic cardiovascular regulation.

“Ongoing symptoms of post-traumatic stress, whether clinically diagnosed or not, are a pervasive problem in the military,” said lead investigator Charles H. Tegeler, professor, Wake Forest Baptist Medical Centre in North Carolina.

“Medications are often used to help control specific symptoms, but can produce side effects. Other treatments may not be well tolerated, and few show a benefit for the associated sleep disturbance. Additional non-invasive, non-drug therapies are needed,” Tegeler added.

In the study, published in the journal Military Medical Research, the team used a high-resolution, relational, resonance-based, electroencephalic mirroring (HIRREM) — a non-invasive method, in which computer software algorithms translate specific brain frequencies into audible tones in real time.

This provides a chance for the brain to listen to itself through an acoustic mirror, Tegeler said.

The results showed reductions in post-traumatic symptoms, including insomnia, depressive mood and anxiety after six months of using the brainwave technology.

The technology works through resonance between brain frequencies and the acoustic stimulation, where the brain is supported to make self-adjustments towards improved balance and reduced hyperarousal. It requires no conscious or cognitive activity.

The net effect is to support the brain to reset stress response patterns that have been rewired by repetitive traumatic events, physical or non-physical, the researchers said. IANS

Intel and Cray Collaborate With U.S. Government, Aims for Nation’s Fastest Computer

The world's current most powerful machine, the Summit supercomputer at Oak Ridge National Laboratory in Tennessee, contains chips from International Business Machines Corp. and Nvidia.

A U.S. government-led group is working with chipmaker Intel and Cray to develop and build the nation’s fastest computer by 2021 for conducting nuclear weapons and other research, officials said Monday.

The Department of Energy and the Argonne National Laboratory near Chicago said they were working on a supercomputer dubbed Aurora with Intel, the world’s biggest supplier of data center chips, and Cray, which specializes in the ultra-fast machines.

The $500 million contract for the project calls on the companies to deliver a computer with so-called exaflop performance — that is, being able to perform 1 quintillion (1,000,000,000,000,000,000) calculations per second.

If the project succeeds, Aurora would represent nearly an order of magnitude leap over existing machines that feature so-called petaflop performance, capable of doing 1 quadrillion (1,000,000,000,000,000) calculations a second.

It also heightens the stakes in a race in which the United States, China, the European Union and Japan have all announced plans to build exaflop-capable supercomputers.

One of Aurora’s primary functions would be simulating nuclear blasts, a pillar of weapons development since the ban of live detonation testings.

Aurora will be built with artificial intelligence capabilities for projects such as developing better battery materials and helping the Department of Veterans Affairs prevent suicides, Rick Stevens, an associate lab director with Argonne overseeing the exascale computing project, said during a news
briefing.

The project is a win for Intel, which will supply its Xeon CPU chips and Optane memory chips for Aurora.

Intel has been fending off rival U.S. chipmaker Nvidia Corp.’s rise in the chip content of supercomputers as the machines take on more artificial intelligence work. Nvidia’s chips are found in five of the world’s current top 10 supercomputers, though the Nvidia chips are found alongside chips from its rivals, according to TOP500, which ranks the machines.

The world’s current most powerful machine, the Summit supercomputer at Oak Ridge National Laboratory in Tennessee, contains chips from International Business Machines Corp. and Nvidia.

The source of chips for supercomputers has become a factor in trade tensions between the United States and China. The world’s third-fastest supercomputer — the Sunway TaihuLight in China — has chips developed domestically in China.

Chirag Dekate, an analyst with Gartner who studies the supercomputing market, said that despite the small contract size relative to Intel’s overall revenue, the work done on Aurora will eventually filter down to the company’s commercial customers.

“It’s not just a jingoistic race between the U.S. and China,” Dekate said. “The innovations that Intel is developing here will percolate down to other parts of its business.” (VOA)
