Tracking the Neurodevelopmental Trajectory of Beta Band Oscillations with Optically Pumped Magnetometer-based Magnetoencephalography

Tracking the Neurodevelopmental Trajectory of Beta Band Oscillations with Optically Pumped Magnetometer-based Magnetoencephalography

Research Background Neural oscillations are fundamental components of brain function, coordinating electrophysiological activities within and between neural assemblies, which is crucial for cognitive and behavioral processes. During children’s growth, the development of these neural processes is not only an important neuroscience issue but also can...

Four-Channel Optically Pumped Magnetometer for a Magnetoencephalography Sensor Array

Four-Channel Optically Pumped Magnetometer for a Magnetoencephalography Sensor Array

Four-Channel Optically Pumped Magnetometer for MEG Sensor Arrays Background Optically Pumped Magnetometers (OPMs) operating in the Spin-Exchange Relaxation-Free (SERF) regime are highly sensitive magnetic field sensors, with sensitivities as low as 0.16 ft/√Hz and 0.54 ft/√Hz. OPMs are based on the interaction between spin-polarized atoms and magne...
