This study uses MEG to show that trigger sounds in misophonia elicit smaller evoked responses and different oscillatory patterns in the right auditory cortex compared to non-trigger sounds.

This paper develops a dynamic field nulling method for wearable OPM-MEG to improve motion tolerance and source localization accuracy during head movements.

The paper compares signal-to-noise ratio (SNR) of MEG signals from on-scalp and off-scalp sensors, finding that OPMs offer better SNR for superficial sources and smaller heads.

The paper examines developmental changes in cortical excitation-inhibition balance in ASD across brain regions and age, finding regionally and developmentally specific differences.

This paper quantifies cerebellar signal detectability in MEG and EEG for epilepsy using anatomically informed source modeling, finding that depth and geometry, not proximity, primarily affect signal-to-noise ratio.

This study finds reduced cortical activation and increased alpha-band functional connectivity in ASD during passive auditory spatial attention tasks compared to typically developing children.

This paper designs and fabricates biplanar nulling coils for OPM-MEG using PCBs, achieving field reduction comparable to traditional methods in a less shielded environment.

The paper investigates whether visual stimuli drive high-frequency activity in human auditory cortex and finds no significant increase in high-frequency activity despite cross-sensory modulations.

The paper uses neural decoding and effective connectivity analysis to identify bilateral posterior temporal cortex as the site of phonological wordform representation, distinct from phonemic or semantic representations.

The paper uses MEG and computational modeling to show that cross-sensory visual input to human auditory cortex is feedback-type, consistent with findings in non-human primates.
