Findings of subarachnoid fat after trauma to a tarlov cyst

open access: yesRadiology Case Reports, 2021
Subarachnoid fat is an uncommon finding that has several etiologies. It is important to determine the etiology in order to plan appropriate treatment. We present a case report of an 80-year-old female brought to the emergency department after a fall with

Appearance of the Optic Nerve Sheath Diameter (ONSD) using Higher Frequency Linear Probes in Detection and Monitoring of Raised Intracranial Pressures-A Cadaveric Study [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2019
Introduction: Trans-bulbar ultrasonography of Optic Nerve Sheath Diameter (ONSD) is increasingly used to detect raised Intracranial Pressures (ICP). Current guidelines for measuring ONSD are based on earlier descriptions of anatomy of optic nerve sheath ...

CSF circulation and dispersion yield rapid clearance from intracranial compartments

open access: yesFrontiers in Bioengineering and Biotechnology, 2022
In this paper, we used a computational model to estimate the clearance of a tracer driven by the circulation of cerebrospinal fluid (CSF) produced in the choroid plexus (CP) located within the lateral ventricles.

Lumbar puncture for the generalist [PDF]

open access: yes, 2004
The safe and successful performance of a lumbar puncture demands a working and yet specific knowledge as well as competency in performance. This review aims to aid understanding of the knowledge framework, the pitfalls and complications of lumbar ...

Aris-Taylor dispersion in the subarachnoid space [PDF]

open access: yesPhysical Review Fluids, 2020
A complete theory able to assess the longitudinal dispersion of a passive solute injected in an annular cavity subject to a pulsatile flow and a porous medium is provided. Aris-Taylor method of statistical moments is combined with the Brinkman approach for porous flows and morphological dispersion, in order to get an analytical relationship for the ...

Mapping Solute Clearance From the Mouse Hippocampus Using a 3D Imaging Cryomicrotome

open access: yesFrontiers in Neuroscience, 2021
The hippocampus is susceptible to protein aggregation in neurodegenerative diseases such as Alzheimer’s disease. This protein accumulation is partially attributed to an impaired clearance; however, the removal pathways for fluids and waste products are ...

ECoG-based short-range recurrent stimulation techniques to stabilize tissue at risk of progressive damage: Theory based on clinical observations [PDF]

open access: yes, 2009
We introduce theoretical concepts based on chaos control to stabilize in acute stroke the tissue at risk of progressive damage by preventing adverse effects of waves of mass neuronal depolarization.
