Respiration shares strong functional links with the brain, influencing perception, emotions and cognition. In turn respiration is modulated by sensory stimuli, attention and vigilance states. To explore this intricate brain-body relationship, we performed intranasal pressure recordings in freely-moving mice paired with extracellular recordings in the CA1 region of the hippocampus to precisely detect Wake, non-REM and REM sleep epochs. We characterized different respiratory cycle features between vigilance states and uncovered unexpected breathing dynamics at transitions between them. To show h
