In the absence of conventional lymphatics, drainage of interstitial fluid and solutes from the brain parenchyma to cervical lymph nodes is along basement membranes in the walls of cerebral capillaries and tunica media of arteries. Perivascular pathways are also involved in the entry of CSF into the brain by the convective influx/glymphatic system. The(More)
In this chapter we describe in detail the surgical and imaging techniques employed for the study of the anatomical routes of drainage of cerebrospinal fluid (CSF) and interstitial fluid (ISF) from the brain. The types of tracers, sites of injection, and volumes injected are crucial. For example, when testing the drainage of ISF from the parenchyma, volumes(More)
