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

The first-ever satellite to test possible solutions in cleaning up space junk has been deployed by the International Space Station (ISS) and would soon begin experiments in orbit.

The Britain-built satellite, named RemoveDEBRIS mission, is one of the world’s first attempts to tackle the build-up of dangerous space debris orbiting the Earth, the British space agency said in a statement late on Friday.

The 100-kg RemoveDebris spacecraft will attempt to capture simulated space debris using a net and a harpoon while also testing advanced cameras and radar systems.

The experiment is important as there are thousands of pieces of space debris circulating the planet, many travelling faster than a speeding bullet, posing a risk to valuable satellites and even the International Space Station itself, the report stated.

Once the experiments are complete, it will unfurl a drag sail to bring itself and the debris out of orbit, where it will burn up as it enters the earth’s atmosphere.

“If successful, the technologies found in RemoveDEBRIS could be included in other missions in the very near future,” said Guglielmo Aglietti, Professor at the University of Surrey.

The RemoveDEBRIS mission is led by the varsity and built by the world’s leading small satellite manufacturer Surrey Satellite Technology Limited (SSTL), with technology on board designed by Airbus.
