Instead, the CSF was pumped back into and through the brain along the outsides of the blood vessels, and as it flushed down into the brain along the outsides of these vessels, it was actually helping to clear away, to clean the waste from the spaces between the brain's cells.
Invece, il CSF veniva pompato  nuovamente all'interno e attraverso il cervello lungo i bordi dei vasi sanguigni, e così mentre fluiva nel cervello lungo i bordi di questi vasi, contribuiva a sgomberare, per pulire i rifiuti dagli spazi tra le cellule del cervello.
