Opportunities for Quantum Sensing in Epilepsy Diagnostics [PDF]
SensorsDiagnosis in epilepsy depends on several distinct objectives—including interictal epileptiform discharge (IED) detection, source localisation of epileptiform activity, and seizure classification—each shaped by the underlying sensing technology.

Simulation Study of Different OPM-MEG Measurement Components. [PDF]
Sensors (Basel), 2022 Magnetoencephalography (MEG) is a neuroimaging technique that measures the magnetic fields of the brain outside of the head. In the past, the most suitable magnetometer for MEG was the superconducting quantum interference device (SQUID), but in recent years, a new type has also been used, the optically pumped magnetometer (OPM).

Characterization of a flexible cap for simultaneous OPM-MEG and EEG measurements
Journal of Neural EngineeringObjective. Combining magnetoencephalography (MEG) and electroencephalography (EEG) can lead to more accurate source reconstruction results. Previous efforts of simultaneous EEG and MEG using optically pumped magnetometers (OPM-MEG) used a two-layer setup,

Development and Application of a Paediatric OPM-MEG System [PDF]
The first few years of life see rapid changes in brain function, as we grow and learn, yet the developing brain remains poorly understood. This is in part due to instrumentational constraints.
