Neuromodulation With Electromagnetic Field Stimulation via Gamma Oscillations Improved Mini-Mental State Examination Scores in Patients With Cognitive Impairment.

This pilot clinical trial evaluated a portable helmet system delivering electromagnetic field stimulation at gamma oscillation frequencies (70100 Hz) in patients with cognitive impairment. Sixteen patients were included, with ten receiving stimulation after protocol refinement. MMSE scores increased on average from…

Validation of Electromagnetic Field Sensor Performance Through Porcine Skulls: Implications for Neurostimulation and Recording Techniques.

This animal validation study tested a Mu-metal-shielded helmet system with proprietary induction sensor stimulators for non-invasive recording and stimulation of neural electromagnetic activity through porcine skulls. The authors report that EMFs penetrated the swine skull and that sensor performance remained…

Localization of Brain Injuries Using Cranial Electromagnetic Fields.

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…

Evaluating the Intrinsic Electromagnetic Field Generated by Neurons From Repetitive Motor Activities in Humans With a Non-contact Non-invasive Electromagnetic Helmet.

This study reports a non-contact, non-invasive helmet system intended to measure intrinsic electromagnetic fields generated by the human brain during stereotyped motor tasks. Volunteers performed repetitive tapping, and the authors report discernible wave changes compared with rest and baseline measurements without a…
