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.

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

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.

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…

Cyanide orientational ordering and copper electric field gradients in CuCN.N2H4.

This study reports solid-state NMR (13C and 15N MAS) measurements on CuCN·N2H4 to extract copper quadrupole coupling constants and characterize cyanide ordering. Ab initio calculations were used to determine electric field gradient and chemical shielding tensor orientations needed for spectral analysis. The authors…

[The impact of treatment by extremely low frequency magnetic fields on the electropotentials in an oral cavity and some chemical elements content in saliva].

This study reports measurements in 25 dental patients treated with the Viofor JPS system using extremely low frequency magnetic fields. Following a series of treatments, oral cavity electropotentials decreased and saliva pH increased. Copper levels in non-stimulated saliva decreased, while other measured elements…
