I'd be intrigued to know what's "new" about this, (unless it's essentially just a novel pathway for CSF drainage that originates solely in the lymphatic system?) As someone with hydrocephalus, I have long had a mechanical device in the ventricles in my brain that drains the excess fluid through a tube that leads from the ventricles, down through my neck & chest, and discharges into a space in my abdominal cavity... (Aren't I 'special'? LOL)
