What forms the cerebrospinal fluid? Cerebrospinal Fluid: The main function of cerebrospinal fluid is to cushion the delicate structures of the central nervous system. Additionally, the cerebrospinal fluid helps distribute nutrients to the central nervous system and remove wastes. ...
What forms the cerebrospinal fluid? How does a nerve impulse passes along a neuron? What is an epithelial tissue? What are the several shapes of neurons depending on their functions? What is the name given to the colored part of the human eye that controls how much light passes through the...
A lumbar puncture (LP) is the insertion of a needle into the spinal canal to collect and examine the fluid that surrounds the brain and spinal cord (cerebral spinal fluid). It is termed a "lumbar puncture" because the needle is placed in the lumbar portion of the back and used to punct...
At the moment, these tests only look for one of the biomarkers of Alzheimer's disease. This means that it can't detect signs of other forms of dementia—and only provides information on one aspect of Alzheimer's disease itself. So even if a person's test comes back negative for Alzheimer...
12 When a radiofrequency pulse sequence with a long time between pulses (2000-3000 milliseconds) and 2 echos (at 20-30 milliseconds and 70-90 milliseconds) is used, the first echo produces a proton-density image that contrasts MS lesions (hyperintense) with the cerebrospinal fluid (hypointense...
However, the complexity of h-tau makes standardization and comparison of MAPT-Tg mouse models challenging. Importantly, while mutations in APP or PS1 cause FAD in humans, mutations in MAPT cause various forms of frontotemporal dementia (FTD) (Poorkaj et al., 1998; Spillantini and Goedert, ...
The cranial fossa is a small depression or cavity in the cranium. There are three main types of cranial fossae are the anterior...

A recent study using 7 T MRI identified cerebrospinal fluid hyperintensities on non-contrast-enhanced-3D FLAIR in CAA patients, which were partially associated with cSS depicted on T2*-weighted image [47]. The cerebrospinal fluid (CSF) hyperintensity on 3D FLAIR and cSS indicates a local and chr...
4-8 However, postmortem studies are not able to measure some aspects of the dopaminergic function, such as dopamine release, and are potentially biased by the effects of antipsychotic treatment and agonal events, whereas the cerebrospinal fluid studies were inconsistent and unable to provide insights...
