Source: Joseph C. Muskat, Vitaliy L. Rayz, and Craig J. Goergen, Weldon School of Biomedical Engineering, Purdue University, West Lafayette, Indiana The objective of this video is to describe recent advancements of computational fluid dynamic (CFD) simulations based on patient- or animal-specific vasculature. Here, subject-based vessel segmentations were created, and, using a combination of open-source and commercial tools, a high-resolution numerical solution was determined within a flow model.

The ventricular cerebrospinal fluid (CSF) bathes the neuroepithelial and cerebral cortical progenitor cells during early brain development in the embryo. Here we describe the method developed to isolate ventricular CSF from rodent embryos of different ages in order to investigate its biological function. In addition, we demonstrate our cerebral cortical explant dissection and culture technique that allows for explant growth with minimal volumes of culture medium or CSF.

Use of Cerebral Open-Flow Microperfusion for the Longitudinal Collection of Interstitial Fluid in an Animal Model of Glioblastoma

In vivo, intercellular communications underpinning many central nervous system diseases, such as glioblastoma (GBM), are notoriously difficult to measure and characterize. Here, we describe procedures of cerebral open-flow microperfusion (cOFM) that can be employed to sample interstitial fluid components in a longitudinal animal model of GBM.

Aneurysmal subarachnoid hemorrhage (SAH) is bleeding that occurs into the subarachnoid space when an aneurysm ruptures. While the morbidity and mortality from this event has been on a decline due to improved treatment approaches, the risk of vasospasm after subarachnoid hemorrhage continues to be the same as it was several years ago. The importance of establishing a comprehensive and reproducible animal model to identify initiating events of cerebral vasospasm has been the focus of research...
FAQs
Reabsorption through arachnoid granulations returns cerebrospinal fluid to venous blood, completing a circulation pathway that begins in the ventricles and passes through connected chambers and the subarachnoid space. This route links fluid movement with continued protection and maintenance of the central nervous system’s chemical environment.
Buoyancy and cushioning help protect neural structures, while waste transport supports neural health. Together, these properties do more than provide physical separation: they help maintain conditions in which the brain and spinal cord can function. This combination explains why cerebrospinal fluid is relevant to both biological research and medical investigation.
The choroid plexus produces cerebrospinal fluid within the brain’s ventricles, placing its entry point at the start of an organized pathway. From there, the fluid moves through connected chambers and into the subarachnoid space before eventual reabsorption. This arrangement links production, circulation, and clearance as coordinated parts of one system.
Researchers obtain cerebrospinal fluid through lumbar puncture for laboratory analysis. The resulting sample provides material for investigating processes affecting the central nervous system, including infection, bleeding, inflammation, and tumors. In this way, lumbar puncture connects fluid physiology with diagnostic investigation and research on neurological disorders.
Analysis can help investigate infections, bleeding, inflammation, tumors, and other neurological disorders. These applications reflect the fluid’s close relationship with the central nervous system and its stable chemical environment. Examining a sample therefore gives researchers and medical investigators a way to study multiple disease-related processes rather than a single condition.
In biology, cerebrospinal fluid provides a context for studying protection, chemical stability, circulation, and waste transport around the brain and spinal cord. In medicine, samples obtained by lumbar puncture support investigation of neurological disorders. Its value therefore spans basic understanding of neural health and applied evaluation of disease-related changes.
