Preprint of collaboration with @lauradata.bsky.social. We found that infraslow slow sighing at a frequency recently linked to glymphatic clearance (0.02-0.03 Hz) produced significantly higher CSF-BOLD coupling than other breathing regimes. www.biorxiv.org/content/10.6...

Effects of different slow paced breathing regimes on cerebrospinal fluid (CSF) oscillations
Cerebrospinal fluid (CSF) transport is crucial for clearing waste from the brain and is largely driven by blood vessel oscillatory dynamics. During non-REM sleep, large oscillations occur in the infra...
