Optimal Frequency for Cranial Electromagnetic Field Stimulation.

Research RF Safe Research Library Jan 1, 2025

This prospective clinical study measured brain electromagnetic field (EMF) patterns in 10 adult patients with traumatic or atraumatic brain injury using a noninvasive 20-sensor helmet within 24 hours of presentation. Using FFT-based analysis, the authors report several targeted frequencies of interest between 5.2 and…

Localization of Brain Injuries Using Cranial Electromagnetic Fields.

Research RF Safe Research Library Jan 1, 2025

This prospective clinical study evaluated a noninvasive portable helmet system to record and localize brain EMF activity in adults with atraumatic brain injury or TBI, including image-negative concussion. Ten patients were enrolled, and abnormal EMF activity was reported to correlate with neurological deficits, CT…

Helmet Radio Frequency Phased Array Applicators Enhance Thermal Magnetic Resonance of Brain Tumors.

Research RF Safe Research Library Jan 1, 2024

This engineering study describes and simulates a helmet radio-frequency phased array applicator for Thermal Magnetic Resonance (ThermalMR), which combines MRI with targeted RF heating. Using EMF and temperature simulations in a phantom and human head model (including a modeled glioblastoma tumor volume), the authors…

Modulation of Inflammatory Response by Electromagnetic Field Stimulation in Traumatic Brain Injury in Yucatan Swine.

Research RF Safe Research Library Jan 1, 2024

This pilot animal study evaluated helmet-delivered EMF stimulation after controlled cortical impact traumatic brain injury in Yucatan miniswine. Three weeks after injury, EMF-treated animals reportedly showed preserved neuronal tissue morphology and reduced inflammatory markers across several measurement platforms.…

The Use of Induction Sensors and Helmet-Based Shielding Technology to Identify Differences in Electromagnetic Fields in Patients With Cranial Neurological Disease Versus Healthy Controls.

Research RF Safe Research Library Jan 1, 2023

This observational study used induction sensors with a Mu-metal and copper mesh shielded helmet to measure cortically generated EMFs in patients with cranial neurological disease and compare patterns to previously obtained healthy control data. Fourteen patients (ages 14–81) were analyzed and compared with four…

A Swine Model of Neural Circuit Electromagnetic Fields: Effects of Immediate Electromagnetic Field Stimulation on Cortical Injury.

Research RF Safe Research Library Jan 1, 2023

This animal study used non-contact induction sensors and a shielded helmet to measure cortical EMF patterns in a Yucatan miniswine before and after traumatic brain injury induced by controlled cortical impact. The authors report that targeted low-frequency EMF stimulation initiated 20 minutes post-injury was…

A Swine Model of Changes in the Neuronal Electromagnetic Field After Traumatic Brain Injury: A Pilot Study.

Research RF Safe Research Library Jan 1, 2023

This pilot swine study evaluated whether non-contact proprietary induction sensors in a Mu-metal/copper mesh helmet can measure endogenous neuronal EMF signals before and after controlled cortical impact traumatic brain injury. The authors report that swine EMF recordings were distinguishable from room noise and…

Measuring the Electromagnetic Field of Human Subjects Using Induction Sensors and a Shielded Helmet Without the Need for a Shielded Room.

Research RF Safe Research Library Jan 1, 2022

This study evaluated whether a lightweight Mu-metal and copper mesh shielded helmet with EMF channels could reduce external electromagnetic interference enough to measure cortically generated EMF using non-contact induction sensors without a shielded room. In five volunteers performing motor, verbalization, and…

Measuring the Electromagnetic Field of the Human Brain at a Distance Using a Shielded Electromagnetic Field Channel.

Research RF Safe Research Library Jan 1, 2022

This study describes a non-contact, non-invasive method to measure electromagnetic activity attributed to the human brain using a lightweight helmet and a shielded EMF channel around a sensor. Volunteers performed metronome-synchronized tasks intended to elicit movement, thoughts of movement, and emotional thought.…
