Breathing significantly modulates brain oscillations across all frequency bands at rest. This study maps these respiration-modulated brain oscillations (RMBOs) throughout the brain, revealing fundamental respiratory-brain coupling.
Area of Science:
- Neuroscience
- Respiratory Physiology
Background:
- Understanding how respiration influences neural signaling is advancing, but its effect on resting brain oscillations remains unclear.
- Previous research suggests links between breathing and brain activity, yet a comprehensive mapping is lacking.
Purpose of the Study:
- To investigate the extent, location, and mechanisms of breathing's modulation of brain oscillations during rest.
- To map respiration-modulated brain oscillations (RMBOs) across the entire brain.
Main Methods:
- Acquired simultaneous respiration and resting-state magnetoencephalography (MEG) data from human participants.
- Utilized phase-amplitude coupling to identify and quantify cyclic modulations in oscillatory amplitudes (2-150 Hz).
Main Results:
- Respiration-modulated brain oscillations (RMBOs) were detected across all major frequency bands.
- Modulations originated from widespread cortical and subcortical networks with distinct spectrotemporal profiles.
- Delta and gamma band modulations showed spatial patterns, stronger at distal cortical sites.
Conclusions:
- This study provides the first comprehensive brain-wide map of RMBOs.
- Respiration-brain coupling is a fundamental mechanism influencing neural processing in resting-state and respiratory control networks (RCNs).

Physiological Control of Respiration
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...
