PATIENTS AND METHODS: The quantitative evaluation of CSF flow in BD and NBD was performed using images obtained at the level of the cerebral aqueduct on the semi-axial plane. The PC-MRI angiography technique was used. RESULTS: There is no distinctive difference between BD and NBD that can be...
The importance of the subarachnoid space (SAS) and the meningeal region, which provides a restraining interface between the brain and the skull during a coup/ countercoup movement of the brain, has been addressed in the literature, [9,10,11]. During a contact or non-contact (angular ...
The glymphatic system is a network of perivascular spaces that promotes movement of cerebrospinal fluid (CSF) into the brain and clearance of metabolic waste. This fluid transport system is supported by the water channel aquaporin-4 (AQP4) localized to vascular endfeet of astrocytes. The glymphatic...
CSF is predominantly, but not exclusively, secreted by the choroid plexuses. Brain interstitial fluid, ependyma and capillaries may also play a poorly defined role in CSF secretion. CSF circulation from sites of secretion to sites of absorption largely depends on the arterial pulse wave. Additional...
CSF. More recently, interest in such questions has been renewed following in vivo observations of rapid transport of a tracer injected into the CSF by Iliff et al.5, who hypothesized that PVS flow constitutes a part of a pathway for clearance of metabolic waste from the brain, which they ...

This is due to administration limited to and localised in the dermis, systemic distribution might be minimised and not interfere with postvaccine antibody production. A clinical case was reported in a child who had rabies exposure on the face, received full dose of ERIG into the wound, sut...
1 The carotid arteries provide about 80% of the blood supply to the brain and thus the majority of emboli from the heart and the proximal aorta also pass through the carotid circulation, which makes it difficult to distinguish between carotid disease and these other sources as the cause for ...
Trace a drop of CSF from where it is secreted to where it is reabsorbed back into the blood stream. Fill in the blanks. The vascular network of the circulatory system is composed of two major subdivisions: the ___ and the ___. Describe the major circulatory...
The disclosure is directed to an implantable device for sensing CSF flow through an implantable ventricular shunt. The sensing device is implanted with the CSF shunt, and includes a
