This randomized, between-subjects study in 98 healthy volunteers tested whether patterned EMF stimulation alters Digit Span performance and EEG activity. Theta-Burst stimulation reduced working memory (Digit Span Backward) and was associated with increased high-alpha activity in frontal regions. Theta-Gamma…

This co-designed provocation study in IEI-EMF volunteers evaluated whether perceived exposure and symptom reporting tracked actual EMF exposure under double-blind conditions. The abstract reports no consistent alignment between perceived exposure certainty or symptoms and true exposure status at the group level, with…

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…

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.…

This study describes a helmet-based, non-contact method to continuously measure electromagnetic field activity associated with human brain neuronal activity during thought tasks. Volunteers performed motor movement, motor imagery, and emotional imagery while brain EMF was recorded. The authors report discernible…

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…

This study describes a lightweight, inexpensive construct using non-contact EMF sensors to measure dynamic electromagnetic fields attributed to the human brain. Measurements in non-clinical volunteers reportedly differed from background recordings and changed during task performance and auditory stimulation. The…

This study enrolled 70 patients with primary hyperthyroidism and 74 healthy volunteers and assessed carotid artery structure and function using ultrasound RF data parameters before and after 131I therapy. Hyperthyroid patients showed worse carotid IMT and stiffness-related measures than controls at baseline. After…

This engineering/clinical MRI methods study evaluated ultrafast volumetric DREAM B1+ mapping to refine patient-adaptive RF shimming at 3T. In 20 patients and three volunteers, a multi-slice adaptive RF shimming approach reduced flip-angle deviations and improved B1+ homogeneity compared with central-slice-based…

This paper describes a new magnetization transfer 31P MRS approach (MT-ISIS) for measuring the creatine kinase forward reaction rate in the human brain using a volume 31P/1H RF coil on a clinical 3-T MRI system. The method aims to reduce acquisition time (30 min), avoid scalp muscle contamination, improve RF…
