Still struggling a bit to work out exactly what these people have found. The report talks of lymphatics where sinuses lie in dura but I wonder if they know what the entry point is like? Thinking about it one might expect there to be continuity with lymphatic vascular structures penetrating into brain tissue along the path of the exiting vein and these might be to some extent compartmentalised off from free CSF. There might even be one cell thick vessels penetrating throughout brain substance. But then there is the question of why you would have these AND 'glymphatic' channels of freely mobile CSF. Or are the glymphatics really the lymphatics after all. In which case it seems likely that the CSF in them is at least partially separate from the bulk pool - maybe completely separate in terms of convective and cellular movement.
