Spatiotemporal Responses to Emotional Conflict and Its Psychiatric Correlates in Adolescents with Epilepsy Using Magnetoencephalography

Spatio-Temporal Responses of Emotional Conflict and Psychiatric Correlation in Adolescent Epilepsy Patients Research Background Epilepsy patients often experience comorbid mental disorders such as depression and anxiety, which negatively impact their quality of life. Emotional regulation is a critical cognitive process that is frequently impaired i...

Reactivation strength during cued recall is modulated by graph distance within cognitive maps

Reactivation Strength in Memory is Modulated by Graph Distance in Cognitive Maps Research Background Memory formation and retrieval are among the crucial areas of research in neuroscience. Classic memory theories propose that memory depends on three distinct stages: encoding, consolidation, and retrieval. New episodic memories are formed through en...

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...

Somatosensory Evoked Spikes in Normal Adults Detected by Magnetoencephalography

Somatosensory Evoked Spikes in Normal Adults Detected by Magnetoencephalography Research Background and Motivation Since 1949, clinical neurophysiology research has discovered that high-voltage cortical somatosensory evoked potentials (SEPs) can be detected in patients with reflex epilepsy, where seizures are triggered by somatosensory stimulation ...

Post-Task Responses Following Working Memory and Movement Are Driven by Transient Spectral Bursts with Similar Characteristics

Background and Research Questions Working memory and post-task responses (PTRs) in the brain have been a focal point in neuroscience research. Previous studies have shown that post-movement beta rebound (PMBR) is a reliable and stable phenomenon in the cerebral cortex that can be studied and measured using magnetoencephalography (MEG). Recent resea...

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...
