This study shows that respiration enhances perceptual sensitivity to near-threshold visual stimuli by modulating arousal, cortical excitability, and neural information flow.

This paper introduces new features for characterizing brain states using MEG data and shows they outperform traditional frequency-based features in classification across participants.

This study uses MEG to examine cortico-cortical and cortico-subcortical connectivity during speech production and listening, finding frequency-specific interactions.

This study dissociates neural tracking of prosodic pauses from multi-word chunk processing using MEG, showing distinct low-frequency brain activity patterns for each.

This study investigates how respiration modulates both periodic and aperiodic brain activity using MEG and EEG data, finding phase-locking of aperiodic activity to the respiratory cycle.

This study maps brain connectivity during continuous speaking and listening using MEG, revealing shared and dissociated neural substrates in different frequency bands.

The paper investigates breathing coordination during speaking and listening, finding inhalation depth correlates with speech envelope power and inhalation alignment during listening to one's own speech.
