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

In view of life-threatening thunderstorms and lightning during the pre-monsoon season, the India Meteorological Department (IMD) has decided to implement an end-to-end prediction system for predicting thunderstorms or lightning by April 2019.

“Last year, during the pre-monsoon season a series of thunderstorm or dust storm affected the northern states and claimed about 200 lives. Hence, the IMD will be implementing an end-to-end prediction system for predicting thunderstorms or lightning by April 2019,” Ministry of earth sciences said in a release on Monday.

Union Minister of Science and Technology, Earth Sciences, Environment, Forests and Climate Change, Dr. Harsh Vardhan said that the Indian Institute of Tropical Meteorology (IITM) and IMD are already working on prediction tools for thunderstorm or lightning.

“IITM Pune has already installed 48 lightning sensors around the country which can locate the thunderstorm/lightning activities in real time. The institute has also developed a mobile app called ‘DAMINI’ to give alerts on impending lightning activity over the area,” Vardhan said while addressing the media here.

Vardhan also informed that currently IITM Pune and IMD are developing a new website for IMD along with the mobile apps for farmers and city forecasts.

“These new tools will help IMD to disseminate forecasts and warnings on time,” he said adding the new website and apps will be ready for launch by June 2019.

Vardhan said that the IMD, in a bid to further strengthen its observational network will install “10 new X-band weather radars” over north-west Himalayas (Jammu and Kashmir, Himachal Pradesh and Uttarakhand) by end of this year.

Also, as per the earth sciences ministry, 11 more C-band radars will be installed by IMD over the plains of India including one over Andaman Nicobar Islands and one over Lakshadweep Islands by 2020.

“In addition, IMD is installing 200 Automated Weather Stations (AWS) at District Agromet Units for providing weather services to farmers and another 200 AWS will be installed over major cities and towns for providing city-specific weather information and forecasts, it said.

“On the specific request from Kerala Government, IMD will also be installing 100 new AWS including rain-gauges to monitor weather activities in the state,” Vardhan’s office said.

In another initiative, Vardhan informed that IITM Pune with the help of IMD and Mumbai Municipal Corporation is installing a new dense rain-gauge network over Mumbai with 200 rain-gauges.

In addition, 4 X-band radars will be also installed so that a merged rainfall data set at 2-kilometre resolution will be prepared and made available to the public in real time.

“This facility will help the city administration and general public to know the prevailing rainfall situation in the city in real-time. For this purpose, a mobile app has already been developed,” the Minister said. (IANS)
