Military personnel may soon be able to eliminate the “guesswork” in diagnosing brain injuries with new soldier-worn tech that tracks brain activity during blast exposure and flags potential signs of trauma in real time.
New findings from US firm Neurable highlight one such platform, the Ops-Core AMP Neuro headset, a hearing protection system fitted with electroencephalography (EEG) sensors.
The device was tested during live training exercises, where soldiers and law enforcement personnel wore it to record brain activity before, during, and after blast exposure.
Blast overpressure from explosives is a known risk factor for mild traumatic brain injury (mTBI), yet most clinical assessments are conducted hours or even days after exposure.
Earlier research points to a critical 10- to 60-minute window when changes in brain activity begin to emerge, though objective data from that period has been limited.
“Moving forward, this technology presents a scalable solution for modernizing range safety,” the white paper stated.
“By transitioning from subjective self-reporting to objective, always-on physiological monitoring, military leadership can make data-driven decisions to mitigate cognitive risk and preserve force readiness.”
Rapid Brain Changes
The latest results show increased Theta and Delta activity in the brain following blast exposure, along with reduced Alpha levels.
These shifts indicate slower brain activity patterns that have been associated with mTBI.
In one case, researchers observed a rise in Theta activity about 10 minutes after a blast, suggesting that neurological effects can begin developing within minutes.
The study also found strong correlations between EEG readings and reported symptoms, including dizziness, vision problems, and difficulty concentrating.
By integrating neural sensors into hearing protection equipment, the tech offers a more immediate layer of brain insight in environments where rapid assessment is critical.
