On-Scalp Optically Pumped Magnetometers versus Cryogenic Magnetoencephalography for Diagnostic Evaluation of Epilepsy in School-aged Children.

, 2022
Background Magnetoencephalography (MEG) is an established method used to detect and localize focal interictal epileptiform discharges (IEDs). Current MEG systems house hundreds of cryogenic sensors in a rigid, one-size-fits-all helmet, which results in ...

Are we in the science fiction era of brain imaging? A point of view on advances and challenges in brain investigation

Aperture Neuro
In recent years, new technologies have been developed to study epilepsy, in particular optically pumped magnetometers. In this editorial, I review some recent work on on-scalp magnetoencephalography in epilepsy and ponder the question: is it science ...

Co‐Doped (Na+, Mg2+, Zn2+, Fe3+)‐Carbonated Hydroxyapatites and Composites with MIIFe2O4: Synthesis, Mechanic, Magnetic, and Antibacterial Properties for Medical Application

ChemistryOpen, Volume 15, Issue 6, June 2026.
Multi‐doped (Na+, Mg2+, Zn2+, CO32‐) hydroxyapatite/ferrite composites were synthesized via a one‐stage method. These “smart” materials exhibit high microhardness (3.28 GPa), potent antimicrobial activity, and membrane‐stabilizing effects, reducing erythrocyte hemolysis by up to 25%.

First Observation of Sawtooth‐Like Undulations in Afternoon Detached Auroral Arcs Modulated by Surface Waves at the Plasmaspheric Plume Boundary

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract The afternoon detached auroral arc is an important phenomenon in the subauroral region, reflecting coupling processes between the Earth's magnetosphere and ionosphere. Previous studies have not identified fine‐scale structures in such arcs, leaving the dynamics underlying their formation poorly understood.

Towards Multi-Class Optically Pumped Magnetometer-Based Brain-Computer Interfaces

Current Directions in Biomedical Engineering
Magnetoencephalography (MEG) using optically pumped magnetometers (OPMs) offers several advantages over electroencephalography (EEG) and superconducting quantum interference device (SQUID)-based MEG, including improved spatial resolution and versatility.

Study of ³He Rabi nutations by optically-pumped cesium magnetometers

, 2017
We describe a method for recording the Rabi nutation of nuclear spin polarized ³He by optically pumped cesium magnetometers. The measurement is performed by detecting the time-dependent magnetic field produced by the 3He magnetization.
