Airway manipulations of respiratory-modulated brain oscillations in humans

In this study, we explore the influence of airway modulation on the phenomenon of breath-brain coupling in humans. Utilizing magnetoencephalography and concurrent breathing measurements, we conducted a comparative analysis of Respiratory-Modulated Brain Oscillations (RMBOs) during oral and nasal breathing. Our findings suggest an association between nasal breathing and the generation of RMBOs. This observation hints at the physiological mechanisms linking respiration and brain activity, highlighting the role of nasal breathing in modulating brain functions. Our work contributes to our understanding of the connections between respiration and brain activity, with implications for both basic neuroscience research and clinical applications.
