Norepinephrine-mediated slow vasomotion drives glymphatic clearance during sleep

What the study found

Synchronized norepinephrine and vascular oscillations were linked to glymphatic CSF flow during NREM sleep; zolpidem dampened key dynamics.

Limitations

Animal study; cannot be translated directly into bedroom design or human treatment recommendations.

Neurodesign interpretation

The architectural inference sits upstream: design can reduce sleep disruptors. It cannot currently be said to 'activate' glymphatic clearance.

Possible design implications

Use only to strengthen the importance of protecting sleep architecture; do not claim a building directly increases glymphatic clearance.

Why it stays in the corpus

Retain as the mechanism paper behind sleep-state brain-clearance claims.
