Insights of posture dependent pressure characteristics in five rats

Current Directions in Biomedical Engineering, 2021
Current shunt treatments of hydrocephalus, a condition characterized by excessive accumulation of cerebrospinal fluid (CSF) and intracranial pressure (ICP) fluctuations, suffer malfunctions caused by changes in patient’s posture.

Neural activity induced by sensory stimulation can drive large-scale cerebrospinal fluid flow during wakefulness in humans

PLoS Biology, 2023
Cerebrospinal fluid (CSF) flow maintains healthy brain homeostasis, facilitating solute transport and the exchange of brain waste products. CSF flow is thus important for brain health, but the mechanisms that control its large-scale movement through the ...

Variations in the cerebrospinal fluid dynamics of the American alligator (Alligator mississippiensis)

Fluids and Barriers of the CNS, 2021
Background Studies of mammalian CSF dynamics have been focused on three things: paravascular flow, pressure and pulsatility, and “bulk” flow; and three (respective) potential motive forces have been identified: vasomotor, cardiac, and ventilatory.

Boundary conditions investigation to improve computer simulation of cerebrospinal fluid dynamics in hydrocephalus patients

Communications Biology, 2021
Seifollah Gholampour et al. develop a computational model to examine the flow of cerebrospinal fluid (CSF) in hydrocephalus patients and healthy controls, and simulate how different biophysical parameters can influence CSF dynamics in the brain ...

Cerebrospinal fluid dynamics correlate with neurogenic claudication in lumbar spinal stenosis.

PLoS ONE, 2021
Neurogenic claudication is a typical manifestation of lumbar spinal stenosis (LSS). However, its pathophysiology is still unclear. The severity of clinical symptoms has been shown not to correlate with the degree of structural stenosis.

Innovations in hydrocephalus modeling: bridging animal models, bioengineering platforms, and precision therapies [PDF]

Exploration of Neuroscience
Hydrocephalus is a complex neurological disease characterized by abnormal cerebrospinal fluid (CSF) accumulation, ventricular enlargement, and progressive neurologic dysfunction. Existing therapies are predominantly surgical, with high complication rates,
